34-346 1.14e-75

C-terminal processing peptidase; serine protease family S41; The C-terminal processing peptidase (CPP, EC 3.4.21.102) also known as tail-specific protease (tsp), the photosystem II D1 C-terminal processing protease (D1P), and other related S41 protease family members are present in this CD. CPP is synthesized as a precursor form with a carboxyl-terminal extension. It specifically recognizes a C-terminal tripeptide, Xaa-Yaa-Zaa, in which Xaa is preferably Ala or Leu, Yaa is preferably Ala or Tyr and Zaa is preferably Ala, but then cleaves at a variable distance from the C-terminus. The C-terminal carboxylate group is essential, and proteins where this group is amidated are not substrates. This family of proteases contains the PDZ domain that promotes protein-protein interactions and is important for substrate recognition. The active site consists of a serine/lysine catalytic dyad. The bacterial CCP-1 is believed to be important for the degradation of incorrectly synthesized proteins as well as protection from thermal and osmotic stresses. In E. coli, it is involved in the cleavage of a C-terminal peptide of 11 residues from the precursor form of penicillin-binding protein 3 (PBP3). In the plant chloroplast, the enzyme removes the C-terminal extension of the D1 polypeptide of photosystem II, allowing the light-driven assembly of the tetranuclear manganese cluster, which is responsible for photosynthetic water oxidation.

34-346 1.14e-75

C-terminal processing peptidase; serine protease family S41; The C-terminal processing peptidase (CPP, EC 3.4.21.102) also known as tail-specific protease (tsp), the photosystem II D1 C-terminal processing protease (D1P), and other related S41 protease family members are present in this CD. CPP is synthesized as a precursor form with a carboxyl-terminal extension. It specifically recognizes a C-terminal tripeptide, Xaa-Yaa-Zaa, in which Xaa is preferably Ala or Leu, Yaa is preferably Ala or Tyr and Zaa is preferably Ala, but then cleaves at a variable distance from the C-terminus. The C-terminal carboxylate group is essential, and proteins where this group is amidated are not substrates. This family of proteases contains the PDZ domain that promotes protein-protein interactions and is important for substrate recognition. The active site consists of a serine/lysine catalytic dyad. The bacterial CCP-1 is believed to be important for the degradation of incorrectly synthesized proteins as well as protection from thermal and osmotic stresses. In E. coli, it is involved in the cleavage of a C-terminal peptide of 11 residues from the precursor form of penicillin-binding protein 3 (PBP3). In the plant chloroplast, the enzyme removes the C-terminal extension of the D1 polypeptide of photosystem II, allowing the light-driven assembly of the tetranuclear manganese cluster, which is responsible for photosynthetic water oxidation.

193-390 1.51e-54

C-terminal processing peptidase family S41; Peptidase family S41 (C-terminal processing peptidase or CTPase family) contains very different subfamilies; it includes photosystem II D1 C-terminal processing protease (CTPase), interphotoreceptor retinoid-binding protein IRBP and tricorn protease (TRI). CTPase and TRI both contain the PDZ domain while IRBP, although being very similar to the tail-specific protease domain, lacks the PDZ insertion domain and hydrolytic activity. These serine proteases have distinctly different active sites: in CTPase, the active site consists of a serine/lysine catalytic dyad while in tricorn core protease, it is a tetrad (serine, histidine, serine, glutamate). CPases with different substrate specificities in different species include processing of D1 protein of the photosystem II reaction center in higher plants and cleavage of a peptide of 11 residues from the precursor form of penicillin-binding protein; and others such as tricorn protease (TRI) act as a carboxypeptidase, involved in the degradation of proteasomal products. CTPase homolog IRBP, secreted by photoreceptors into the interphotoreceptor matrix, having arisen in the early evolution of the vertebrate eye, promotes the release of all-trans retinol from photoreceptors and facilitates its delivery to the retinal pigment epithelium.

166-337 3.39e-18

C-terminal processing peptidase-like; serine protease family S41; Bacterial protease homologs of the S41 family related to C-terminal processing peptidase (CPP). CPP-1 is believed to be important for the degradation of incorrectly synthesized proteins as well as protection from thermal and osmotic stresses. CPP is synthesized with an extension on its carboxyl-terminus and specifically recognizes a C-terminal tripeptide, but cleaves at variable distance from the C-terminus. The CPP active site consists of a serine/lysine catalytic dyad. Conservation of these residues is seen in the CPP-like proteins of this group. CPP proteins contain a PDZ domain that promotes protein-protein interactions and is important for substrate recognition however, most of CPP-like proteins only have an internal fragment or lack the PDZ domain.

94-177 5.87e-17

circularly permuted PDZ domain of C-terminal processing peptidase (CPP), a serine protease, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of CPP (also known as tail-specific protease, PRC protein, Protease Re, and Photosystem II D1 protein processing peptidase), and related domains. CPP belongs to the peptidase S41A family. It cleaves a C-terminal 11 residue peptide from the precursor form of penicillin-binding protein 3, and may have a role in protecting bacterium from thermal and osmotic stresses. In the plant chloroplast, the enzyme removes the C-terminal extension of the D1 polypeptide of photosystem II. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This CPP-like PDZ domain is a circularly permuted PDZ domain which places beta-strand A on the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus.

193-389 2.79e-16

Interphotoreceptor retinoid-binding protein; serine protease family S41; Interphotoreceptor retinoid-binding protein (IRBP) is a homolog of the S41 protease, C-terminal processing peptidase (CTPase) family. It is thought to facilitate the compartmentalization of the visual cycle that requires poorly soluble and potentially toxic retinoids to cross the aqueous subretinal space between the photoreceptors and the retinal pigment epithelium (RPE). IRBP is secreted by photoreceptors into the interphotoreceptor matrix (IPM) where it is rapidly turned over by a combination of RPE and photoreceptor endocytosis. It is the most abundant soluble protein component of the IPM, consisting of homologous modules, each repeat structure arising through the duplication (as in teleost IRBP) or quadruplication (in tetrapods) of an ancient gene, arisen in the early evolution of the vertebrate eye. IRBP has been shown to promote the release of all-trans retinol from photoreceptors and facilitates its delivery to the RPE. Conversely, IRBP can promote the release of 11-cis-retinal from the RPE, prevent its isomerization in the subretinal space, and transfer it to photoreceptors. In vivo evidence implicates IRBP as a retinoid transporter in the visual cycle, suggesting a critical role for IRBP in cone function essential for human vision. IRBP is a dominant autoimmune antigen in the eye; IRBP proteolysis analysis has proven a useful biomarker for autoimmune uveitis (AU) disorders, a major cause of blindness. This family also includes a chlamydia-secreted protein, designated chlamydia protease-like activity factor (CPAF), known to degrade host proteins, enabling Chlamydia to evade host defenses and replicate.

189-345 3.18e-14

Tricorn protease; serine protease family S41; The tricorn protease (TRI), a member of the S41 peptidase family and named for its tricorn-like shape, exists only in some archaea and eubacteria. It has been shown to act as a carboxypeptidase, involved in the degradation of proteasomal products to preferentially yield di- and tripeptides, with subsequent and final degradations to free amino acid residues by tricorn interacting factors, F1, F2 and F3. Tricorn is a hexameric D3-symmetric protease of 720kD, and can self-associate further into a giant icosahedral capsid structure containing twenty copies of the complex. Each tricorn peptidase monomer consists of five structural domains: a six-bladed beta-propeller and a seven-bladed beta-propeller that limit access to the active site, the two domains (C1 and C2) that carry the active site residues, and a PDZ-like domain (proposed to be important for substrate recognition) between the C1 and C2 domains. The active site tetrad residues are distributed between the C1 and C2 domains, with serine and histidine on C1 and serine and glutamate on C2.

circularly permuted PDZ domains of Escherichia coli Regulator of sigma-E protease (RseP) and related domains; Permuted PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of ResP (also known as Site-2 protease RseP, and YaeL), and related domains. RseP is involved in the regulation of an extracytoplasmic stress response through the cleavage of membrane-spanning anti-stress-response transcription factor (anti-sigmE) protein RseA; it cleaves the peptide bond between the critical alanine and cysteine in the transmembrane region of RseA, releasing the cytoplasmic domain of RseA with its associated sigmaE. RseP contains two tandem-arranged periplasmic PDZ domains (PDZ-N/PDZ1 and PDZ-C/PDZ2) which act to negatively regulate protease action on intact RseA; they serve as a size-exclusion filter which prevents the access of an intact RseA into the active site of RseP. PDZ domains usually bind in sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This RseP family PDZ domain is a circularly permuted PDZ domain which places both beta-strands A and B at the C-terminus. Another permutation exists in the PDZ superfamily which places beta-strand A at the C-terminus.

Typically, these proteases have an N-terminal serine protease domain and at least one C-terminal PDZ domain that recognizes substrates, and in some cases activates the protease function. An exception is yeast Nma11p which has two protease domains and four PDZ domains; its N-terminal half is comprised of a protease domain, followed by two PDZ domains, and its C-terminal half has a similar domain arrangement. HtrA-type proteases include the human HtrA1-4 and MBTPS2, tricorn protease, DegS, DegP and C-terminal processing peptidase, cyanobacterial serine proteases Hhoa, HhoB, and HtrA, and yeast Nma11p. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-termini of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This Deg/HtrA family PDZ domain is a circularly permuted PDZ domain which places beta-strand A at the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus.

109-169 9.43e-08

circularly permuted first PDZ domain (PDZ1) of Escherichia coli periplasmic serine endoprotease DegP and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of Escherichia coli DegP (also known as heat shock protein DegP and Protease Do) and related domains. DegP belongs to the HtrA family of housekeeping proteases. It acts as a protease, degrading transiently denatured and unfolded or misfolded proteins which accumulate in the periplasm following heat shock or other stress conditions, and as a molecular chaperone at low temperatures. DegP has two PDZ domains in addition to the protease domain; its PDZ1 domain is responsible for identifying the distinct substrate sequences that affect degradation (degron) of the substrate sequence, and its PDZ2 domain is responsible for combining with other DegP monomers to form a stable oligomer structure. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This DegP family PDZ domain 1 is a circularly permuted PDZ domain which places beta-strand A on the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus.

circularly permuted PDZ domain of Bacillus subtilis HtrA-type serine proteases HtrA, HtrB, and YyxA and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of Bacillus subtilis HtrA/YkdA, HtrB/YvtA and YyxA/YycK, and related domains. HtrA-type serine proteases participate in folding and degradation of aberrant proteins, and in processing and maturation of native proteins. HtrA, HtrB, and YyxA have a single transmembrane domain at the N-terminus and a PDZ domain at the C-terminus. Expression of htrA and htrB genes is induced both by heat shock and by secretion stress (by a common) mechanism; yyxA is neither heat shock nor secretion stress inducible. HtrA and HtrB may have overlapping cellular functions; YyxA may have a cellular function distinct from the other two proteases or have the same function but under different conditions. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands.

109-176 6.12e-06

periplasmic serine protease, Do/DeqQ family; This family consists of a set proteins various designated DegP, heat shock protein HtrA, and protease DO. The ortholog in Pseudomonas aeruginosa is designated MucD and is found in an operon that controls mucoid phenotype. This family also includes the DegQ (HhoA) paralog in E. coli which can rescue a DegP mutant, but not the smaller DegS paralog, which cannot. Members of this family are located in the periplasm and have separable functions as both protease and chaperone. Members have a trypsin domain and two copies of a PDZ domain. This protein protects bacteria from thermal and other stresses and may be important for the survival of bacterial pathogens.// The chaperone function is dominant at low temperatures, whereas the proteolytic activity is turned on at elevated temperatures.

PDZ domain 1 of syntenin-1, syntenin-2, and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain 1 of syntenin-1, syntenin-2, and related domains. Syntenins are implicated in various cellular processes such as trafficking, signaling, and cancer metastasis. They bind to signaling and adhesion molecules, such as syndecans, neurexins, ephrin B, and phospholipid PIP2. Through its tandem PDZ domains (PDZ1 and PDZ2), syntenin links syndecans to other cell surface receptors and kinases, such as E-cadherin and ephrin-B, establishing signaling crosstalk. During syndecan binding, syntenin PDZ2 serves as a high-affinity domain, and PDZ1, also necessary for binding, acts as a complementary, low-affinity domain; this is also the case for syntenin binding to proto-oncogene c-Src. The syntenin PDZ domain-PIP2 interaction controls Arf6-mediated syndecan recycling through endosomal compartments; both PDZ1 and PDZ2 interact with PIP2. Different binding partners and downstream regulators of syntenin1 PDZ domains, such as to proto-oncogene c-Src, mitogen-activated protein kinase (MAPK), and focal adhesion kinase (FAK), have been identified that promote the progression and invasion of a variety of cancers, such as melanoma, glioblastoma multiforme and breast cancer. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This syntenin-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged as beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta- strand F.

circularly permuted PDZ domain of DegS serine endoprotease; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of Escherichia coli DegS and related domains. DegS (also known as Site-1 protease DegS, S1P protease DegS, and Site-1-type intramembrane protease) participates in the activation of the sigma(E) extracytoplasmic stress response. Initially, there is an accumulation of misfolded membrane proteins (OMPs) in the periplasm which bind by their YXF motif to the DegS PDZ domain, activating DegS-catalyzed cleavage of the RseA periplasmic domain and making RseA a substrate for cleavage by another membrane protease RseP. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands.

PDZ domains of the Na+/H+ exchange regulatory cofactor (NHERF) family (NHERF1-4), and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of the Na+/H+ exchange regulatory cofactor (NHERF) family of multi-PDZ-domain-containing scaffolding proteins (NHERF1-4), and related domains. The NHERF family includes NHERF1 (also known as EBP50), NHERF2 (also known as E3KARP; TKA-1; SIP-1), NHERF3 (also known as CAP70; CLAMP; Napi-Cap-1; PDZD1) and NHERF4 (also known as IKEPP; PDZK2; Napi-Cap-2). NHERF1 and NHERF2 have tandem PDZ domains (PDZ1-2); NHERF3 and NHERF4 have four PDZ domains (PDZ1-4). NHERFs are involved in the regulation of multiple receptors or transporters, such as type II sodium-phosphate cotransporter (Npt2a), purinergic P2Y1 receptor P2Y1R, the beta2-adrenergic receptor (beta2-AR), parathyroid hormone receptor type 1 (PTHR), the lysophosphatidic acid receptors (LPARs), sodium-hydrogen exchanger 3 (NHE3), and cystic fibrosis transmembrane conductance regulator (CFTR). NHERF-PDZ1 domain interaction partners include Npt2a, purinergic P2Y1 receptor, beta2-AR, CFTR, PTHR, NH3, G-protein-coupled receptor kinase 6 (GRK6A), platelet-derived growth factor receptor (PDGFR), B1 subunit of the H+ATPase, cholesterol, receptor for activated C-kinase RACK1, aquaporin 9, among others. The NHERF PDZ2 domain interacts with fewer proteins: NHERF1 PDZ2 binds Npt2a, PTHR, beta-catenin, aquaporin 9, and RACK1; NHERF2 PDZ2 binds LPA2, P2Y1R, and NHE3, cGMP-dependent protein kinase type II (cGKII). NHERF4 PDZ1 and PDZ4 bind the epithelial Ca(2+) channels TRPV5 and TRPV6. NHERF2/NHERF3 heterodimerization is mediated by PDZ domains of NHERF2 and the C-terminal PDZ domain recognition motif of NHERF3. NHERF4 regulates several transporters mediating influx of xenobiotics and nutrients in the small intestine. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands.

Rhophilin-1 (RHPN1, also known as GTP-Rho-binding protein 1) and rhophilin-2 (RHPN2, also known as GTP-Rho-binding protein 2) are Rho-GTP binding proteins involved in cytoskeletal dynamics. Rhophilin-2 inhibits RhoA's activity to induce F-actin stress fibers. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains as well as those with circular permutations and domain swapping mediated by beta-strands. This rhophilin-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.
