M20 Peptidase D has specificity for beta-alanyl-L-histidine dipeptide; Peptidase M20 family, ...
17-488 0e+00

M20 Peptidase D has specificity for beta-alanyl-L-histidine dipeptide; Peptidase M20 family, Peptidase D (PepD, Xaa-His dipeptidase; X-His dipeptidase; aminoacylhistidine dipeptidase; dipeptidase D; Beta-alanyl-histidine dipeptidase; pepD g.p. (Escherichia coli); EC 3.4.13.3) subfamily. PepD is a cytoplasmic enzyme family characterized by its unusual specificity for the dipeptides beta-alanyl-L-histidine (L-carnosine or beta-Ala-His) and gamma-aminobutyryl histidine (L-homocarnosine or gamma-amino-butyl-His). Homocarnosine has been suggested as a precursor for the neurotransmitter gamma-aminobutyric acid (GABA), acting as a GABA reservoir, and may mediate anti-seizure effects of GABAergic therapies. It has also been reported that glucose metabolism could be influenced by L-carnosine. PepD also includes a lid domain that forms a homodimer; however, the physiological function of this extra domain remains unclear.

Xaa-His dipeptidase; This model represents a clade of dipeptidase enzymes, many of which are specific for carnosine (beta-alanyl-histidine). This enzymes is found broadly in bacteria and at least one archaeon (Methanosarcina). In most species there is only one sequence hitting this model, while Bacteroides thetaiotaomicron, Chlorobium tepidum and Clostridium perfringens have two each and Fusobacterium nucleatum has three. These may indicate that there is a broader substrate range than just carnosine in these (and other) species. 8/19/03 GO terms added [SS]

M20 Peptidase D has specificity for beta-alanyl-L-histidine dipeptide; Peptidase M20 family, Peptidase D (PepD, Xaa-His dipeptidase; X-His dipeptidase; aminoacylhistidine dipeptidase; dipeptidase D; Beta-alanyl-histidine dipeptidase; pepD g.p. (Escherichia coli); EC 3.4.13.3) subfamily. PepD is a cytoplasmic enzyme family characterized by its unusual specificity for the dipeptides beta-alanyl-L-histidine (L-carnosine or beta-Ala-His) and gamma-aminobutyryl histidine (L-homocarnosine or gamma-amino-butyl-His). Homocarnosine has been suggested as a precursor for the neurotransmitter gamma-aminobutyric acid (GABA), acting as a GABA reservoir, and may mediate anti-seizure effects of GABAergic therapies. It has also been reported that glucose metabolism could be influenced by L-carnosine. PepD also includes a lid domain that forms a homodimer; however, the physiological function of this extra domain remains unclear.

Xaa-His dipeptidase; This model represents a clade of dipeptidase enzymes, many of which are specific for carnosine (beta-alanyl-histidine). This enzymes is found broadly in bacteria and at least one archaeon (Methanosarcina). In most species there is only one sequence hitting this model, while Bacteroides thetaiotaomicron, Chlorobium tepidum and Clostridium perfringens have two each and Fusobacterium nucleatum has three. These may indicate that there is a broader substrate range than just carnosine in these (and other) species. 8/19/03 GO terms added [SS]

Peptidase M20 acetylornithine deacetylase/succinyl-diaminopimelate desuccinylase (ArgE/DapE)-like; Peptidase M20 acetylornithine deacetylase/succinyl-diaminopimelate desuccinylase (ArgE/DapE) like family of enzymes catalyze analogous reactions and share a common activator, the metal ion (usually Co2+ or Zn2+). ArgE catalyzes a broad range of substrates, including N-acetylornithine, alpha-N-acetylmethionine and alpha-N-formylmethionine, while DapE catalyzes the hydrolysis of N-succinyl-L,L-diaminopimelate (L,L-SDAP) to L,L-diaminopimelate and succinate. Proteins in this family are mostly bacterial and have been inferred by homology as being related to both ArgE and DapE. This family also includes N-acetyl-L-citrulline deacetylase (ACDase; acetylcitrulline deacetylase), a unique, novel enzyme found in Xanthomonas campestris, a plant pathogen, in which N-acetyl-L-ornithine is the substrate for transcarbamoylation reaction, and the product is N-acetyl-L-citrulline. Thus, in the arginine biosynthesis pathway, ACDase subsequently catalyzes the hydrolysis of N-acetyl-L-citrulline to acetate and L-citrulline.

30-175 1.56e-12

M20 Peptidase T like enzymes specifically cleave tripeptides; Peptidase M20 family, PeptT (tripeptide aminopeptidase; tripeptidase)-like subfamily. This group includes bacterial tripeptidases as well as predicted tripeptidases. Peptidase T acts only on tripeptide substrates, and is thus called a tripeptidase. It catalyzes the release of N-terminal amino acids with hydrophobic side chains from tripeptides with high specificity; dipeptides, tetrapeptides or tripeptides with the N-terminus blocked are not cleaved. Tripeptidases are known to function at the final stage of proteolysis in lactococcal bacteria and release amino acids from tripeptides produced during the digestion of milk proteins such as casein.

58-169 8.41e-10

M20, M18 and M42 Zn-peptidases include aminopeptidases and carboxypeptidases; This family corresponds to the MEROPS MH clan families M18, M20, and M42. The peptidase M20 family contains exopeptidases, including carboxypeptidases such as the glutamate carboxypeptidase from Pseudomonas, the thermostable carboxypeptidase Ss1 of broad specificity from archaea and yeast Gly-X carboxypeptidase, dipeptidases such as bacterial dipeptidase, peptidase V (PepV), a eukaryotic, non-specific dipeptidase, and two Xaa-His dipeptidases (carnosinases). This family also includes the bacterial aminopeptidase peptidase T (PepT) that acts only on tripeptide substrates and has therefore been termed a tripeptidase. These peptidases generally hydrolyze the late products of protein degradation so as to complete the conversion of proteins to free amino acids. Glutamate carboxypeptidase hydrolyzes folate analogs such as methotrexate, and therefore can be used to treat methotrexate toxicity. Peptidase families M18 and M42 contain metallo-aminopeptidases. M18 (aspartyl aminopeptidase, DAP) family cleaves only unblocked N-terminal acidic amino-acid residues and is highly selective for hydrolyzing aspartate or glutamate residues. Some M42 (also known as glutamyl aminopeptidase) enzymes exhibit aminopeptidase specificity while others also have acylaminoacyl-peptidase activity (i.e. hydrolysis of acylated N-terminal residues).

58-176 2.22e-09

Zinc peptidases M18, M20, M28, and M42; Zinc peptidases play vital roles in metabolic and signaling pathways throughout all kingdoms of life. This hierarchy contains zinc peptidases that correspond to the MH clan in the MEROPS database, which contains 4 families (M18, M20, M28, M42). The peptidase M20 family includes carboxypeptidases such as the glutamate carboxypeptidase from Pseudomonas, the thermostable carboxypeptidase Ss1 of broad specificity from archaea and yeast Gly-X carboxypeptidase. The dipeptidases include bacterial dipeptidase, peptidase V (PepV), a non-specific eukaryotic dipeptidase, and two Xaa-His dipeptidases (carnosinases). There is also the bacterial aminopeptidase, peptidase T (PepT) that acts only on tripeptide substrates and has therefore been termed a tripeptidase. Peptidase family M28 contains aminopeptidases and carboxypeptidases, and has co-catalytic zinc ions. However, several enzymes in this family utilize other first row transition metal ions such as cobalt and manganese. Each zinc ion is tetrahedrally co-ordinated, with three amino acid ligands plus activated water; one aspartate residue binds both metal ions. The aminopeptidases in this family are also called bacterial leucyl aminopeptidases, but are able to release a variety of N-terminal amino acids. IAP aminopeptidase and aminopeptidase Y preferentially release basic amino acids while glutamate carboxypeptidase II preferentially releases C-terminal glutamates. Glutamate carboxypeptidase II and plasma glutamate carboxypeptidase hydrolyze dipeptides. Peptidase families M18 and M42 contain metallo-aminopeptidases. M18 is widely distributed in bacteria and eukaryotes. However, only yeast aminopeptidase I and mammalian aspartyl aminopeptidase have been characterized in detail. Some M42 (also known as glutamyl aminopeptidase) enzymes exhibit aminopeptidase specificity while others also have acylaminoacyl-peptidase activity (i.e. hydrolysis of acylated N-terminal residues).

M20 Peptidase Glutamate carboxypeptidase, a periplasmic enzyme; Peptidase M20 family, Glutamate carboxypeptidase (carboxypeptidase G; carboxypeptidase G1; carboxypeptidase G2; CPDG2; CPG2; Folate hydrolase G2; Pteroylmonoglutamic acid hydrolase G2; Glucarpidase; E.C. 3.4.17.11) subfamily. CPDG2 is a periplasmic enzyme that is synthesized with a signal peptide. It is a dimeric zinc-dependent exopeptidase, with two domains, a catalytic domain, which provides the ligands for the two zinc ions in the active site, and a dimerization domain. CPDG2 cleaves the C-terminal glutamate moiety from a wide range of N-acyl groups, including peptidyl, aminoacyl, benzoyl, benzyloxycarbonyl, folyl, and pteroyl groups to release benzoic acid, phenol, and aniline mustards. It is used clinically to treat methotrexate toxicity by hydrolyzing it to inactive and non-toxic metabolites. It is also proposed for use in antibody-directed enzyme prodrug therapy; for example, glutamate can be cleaved from glutamated benzoyl nitrogen mustards, producing nitrogen mustards with effective cytotoxicity against tumor cells.

M20 Peptidase acetylornithine deacetylase/acetyl-lysine deacetylase; Peptidase M20 family, ...
15-159 1.16e-05

M20 Peptidase acetylornithine deacetylase/acetyl-lysine deacetylase; Peptidase M20 family, acetylornithine deacetylase (ArgE)/acetyl-lysine deacetylase (LysK) subfamily. Proteins in this subfamily are mainly archaeal with related bacterial species and are deacetylases with specificity for both N-acetyl-ornithine and N-acetyl-lysine found within a lysine biosynthesis operon. ArgE catalyzes the conversion of N-acetylornithine to ornithine, while LysK, a homolog of ArgE, has deacetylating activities for both N-acetyllysine and N-acetylornithine at almost equal efficiency. These results suggest that LysK which may share an ancestor with ArgE functions not only for lysine biosynthesis, but also for arginine biosynthesis in species such as Thermus thermophilus. The substrate specificity of ArgE is quite broad in that several alpha-N-acyl-L-amino acids can be hydrolyzed, including alpha-N-acetylmethionine and alpha-N-formylmethionine. ArgE shares significant sequence homology and biochemical features, and possibly a common origin, with glutamate carboxypeptidase (CPG2) and succinyl-diaminopimelate desuccinylase (DapE), and aminoacylase I (ACY1), having all metal ligand binding residues conserved.

PepT acts only on tripeptide substrates, and is thus called a tripeptidase. It catalyzes the release of N-terminal amino acids with hydrophobic side chains from tripeptides with high specificity; dipeptides, tetrapeptides or tripeptides with the N-terminus blocked are not cleaved. Tripeptidases are known to function at the final stage of proteolysis in lactococcal bacteria and release amino acids from tripeptides produced during the digestion of milk proteins such as casein.

uncharacterized M20 dipeptidase; Peptidase M20 family, unknown dipeptidase-like subfamily (inferred by homology to be dipeptidases). M20 dipeptidases include a large variety of bacterial enzymes including cytosolic nonspecific dipeptidase (CNDP), Xaa-methyl-His dipeptidase (anserinase),and canosinase. These dipeptidases have been shown to act on a wide range of dipeptides, but not larger peptides. For example, anserinase mainly catalyzes the hydrolysis of N-alpha-acetylhistidine while carnosinase degrades beta-alanyl-L-histidine. This family includes dapE (Lpg0809) from Legionella pneumophila.

M20 Peptidases with similarity to acetylornithine deacetylases; Peptidase M20 family, ...

M20 Peptidases with similarity to acetylornithine deacetylases; Peptidase M20 family, acetylornithine deacetylase (ArgE, Acetylornithinase, AO, N2-acetyl-L-ornithine amidohydrolase, EC 3.5.1.16)-related subfamily. Proteins in this subfamily have not yet been characterized, but have been predicted to have deacetylase activity. ArgE catalyzes the conversion of N-acetylornithine to ornithine, which can then be incorporated into the urea cycle for the final stage of arginine synthesis. The substrate specificity of ArgE is quite broad; several alpha-N-acyl-L-amino acids can be hydrolyzed, including alpha-N-acetylmethionine and alpha-N-formylmethionine. ArgE shares significant sequence homology and biochemical features, and possibly a common origin, with glutamate carboxypeptidase (CPG2) and succinyl-diaminopimelate desuccinylase (DapE), and aminoacylase I (ACY1), having all metal ligand binding residues conserved.

M20 Peptidase Xaa-His dipeptidase (PepV) degrades hydrophobic dipeptides; Peptidase M20 family, ...
236-436 9.46e-04

M20 Peptidase Xaa-His dipeptidase (PepV) degrades hydrophobic dipeptides; Peptidase M20 family, Peptidase V (Xaa-His dipeptidase; PepV g.p. (Lactobacillus lactis); X-His dipeptidase; beta-Ala-His dipeptidase; carnosinase) subfamily. The PepV group of proteins is widely distributed in lactic acid bacteria. PepV, along with PepT, functions at the end of the proteolytic processing system. PepV is a monomeric metalloenzyme that preferentially degrades hydrophobic dipeptides. The Streptococcus gordonii PepV gene is homologous to the PepV gene family from Lactobacillus and Lactococcus spp. PepV recognizes and fixes the dipeptide backbone, while the side chains are not specifically probed and can vary, rendering it a nonspecific dipeptidase. It has been shown that Lactococcus lactis subspecies lactis (L9) PepV does not hydrolyze dipeptides containing Pro or D-amino acids at the C-terminus, while PepV from Lactobaccilus has been shown to have L-carnosine hydrolyzing activity. The mammalian PepV also acts on anserine and homocarnosine (but not on homoanserine), and to a lesser extent on some other aminoacyl-L-histidine dipeptides. Also included is the Staphylococcus aureus metallopeptidase, Sapep, a Mn(2+)-dependent dipeptidase where large interdomain movements could potentially regulate the activity of this enzyme.
