pp-GalNAc-T initiates the formation of mucin-type O-linked glycans; UDP-GalNAc: polypeptide alpha-N-acetylgalactosaminyltransferases (pp-GalNAc-T) initiate the formation of mucin-type, O-linked glycans by catalyzing the transfer of alpha-N-acetylgalactosamine (GalNAc) from UDP-GalNAc to hydroxyl groups of Ser or Thr residues of core proteins to form the Tn antigen (GalNAc-a-1-O-Ser/Thr). These enzymes are type II membrane proteins with a GT-A type catalytic domain and a lectin domain located on the lumen side of the Golgi apparatus. In human, there are 15 isozymes of pp-GalNAc-Ts, representing the largest of all glycosyltransferase families. Each isozyme has unique but partially redundant substrate specificity for glycosylation sites on acceptor proteins.

 463-604 4.63e-104

ricin B-type lectin domain, beta-trefoil fold, found in polypeptide N-acetylgalactosaminyltransferase 18 (GALNT18) and similar proteins; GALNT18 (EC 2.4.1.41), also called polypeptide GalNAc transferase 18, GalNAc-T18, polypeptide GalNAc transferase-like protein 4, GalNAc-T-like protein 4, pp-GaNTase-like protein 4, polypeptide N-acetylgalactosaminyltransferase-like protein 4, protein-UDP acetylgalactosaminyltransferase-like protein 4, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase-like protein 4, catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT18 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.

In human, there are 15 isozymes of pp-GalNAc-Ts, representing the largest of all glycosyltransferase families. Each isozyme has unique but partially redundant substrate specificity for glycosylation sites on acceptor proteins.

ricin B-type lectin domain, beta-trefoil fold, found in polypeptide N-acetylgalactosaminyltransferase 18 (GALNT18) and similar proteins; GALNT18 (EC 2.4.1.41), also called polypeptide GalNAc transferase 18, GalNAc-T18, polypeptide GalNAc transferase-like protein 4, GalNAc-T-like protein 4, pp-GaNTase-like protein 4, polypeptide N-acetylgalactosaminyltransferase-like protein 4, protein-UDP acetylgalactosaminyltransferase-like protein 4, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase-like protein 4, catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT18 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.

ricin B-type lectin domain, beta-trefoil fold, found in Drosophila melanogaster polypeptide N-acetylgalactosaminyltransferase 3 (Pgant3) and similar proteins; Pgant3, also called pp-GaNTase 3, protein-UDP acetylgalactosaminyltransferase 3, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 3, functions as a GalNAc transferase (EC 2.4.1.41) that catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Pgant3 can both act as a peptide transferase that transfers GalNAc onto unmodified peptide substrates, and as a glycopeptide transferase that requires the prior addition of a GalNAc on a peptide before adding additional GalNAc moieties. It prefers EA2 as a substrate and has weak activity toward Muc5AC-3, -13 and -3/13 substrates. Pgant3 plays a critical role in the regulation of integrin-mediated cell adhesion during wing development by influencing, via glycosylation, the secretion and localization of the integrin ligand Tig to the basal cell layer interface. It may have a role in protein O-glycosylation in the Golgi and thereby in establishing and/or maintaining a proper secretory apparatus structure. Together with Pgant35A, Pgant3 regulates integrin levels and activity-dependent integrin signaling at the synapse in neurons and muscles. Members of this subfamily contain a ricin B-type lectin domain at the C-terminus. The ricin B-type lectin domain shows a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain bears a potential sugar binding site.

 470-601 2.10e-10

ricin B-type lectin domain, beta-trefoil fold, found in the polypeptide N-acetylgalactosaminyltransferase 3 (GALNT3)-like subfamily; The GALNT3-like subfamily includes GALNT3, GALNT4, GALNT6 and GALNT12. They act as GalNAc transferases (EC 2.4.1.41) that catalyze the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT3 has activity toward HIV envelope glycoprotein gp120, EA2, Muc2 and Muc5. It probably glycosylates fibronectin in vivo as well as FGF23. It plays a central role in phosphate homeostasis. GALNT4 shows highest activity towards Muc7, EA2 and Muc2, with a lower activity compared to GALNT2. It glycosylates 'Thr-57' of SELPLG. GALNT6 may participate in the synthesis of oncofetal fibronectin. It has activity toward Muc1a, Muc2, EA2 and fibronectin peptides. GALNT12 has activity toward non-glycosylated peptides such as Muc5AC, Muc1a and EA2, and no detectable activity with non-glycosylated Muc2 and Muc7. It displays enzymatic activity toward the Gal-NAc-Muc5AC glycopeptide, but no detectable activity to mono-GalNAc-glycosylated Muc1a, Muc2, Muc7 and EA2. It may play an important role in the initial step of mucin-type oligosaccharide biosynthesis in digestive organs. Members of this family comprise a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which are characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.

 160-319 6.00e-09

Glycosyltransferase family A (GT-A) includes diverse families of glycosyl transferases with a common GT-A type structural fold; Glycosyltransferases (GTs) are enzymes that synthesize oligosaccharides, polysaccharides, and glycoconjugates by transferring the sugar moiety from an activated nucleotide-sugar donor to an acceptor molecule, which may be a growing oligosaccharide, a lipid, or a protein. Based on the stereochemistry of the donor and acceptor molecules, GTs are classified as either retaining or inverting enzymes. To date, all GT structures adopt one of two possible folds, termed GT-A fold and GT-B fold. This hierarchy includes diverse families of glycosyl transferases with a common GT-A type structural fold, which has two tightly associated beta/alpha/beta domains that tend to form a continuous central sheet of at least eight beta-strands. The majority of the proteins in this superfamily are Glycosyltransferase family 2 (GT-2) proteins. But it also includes families GT-43, GT-6, GT-8, GT13 and GT-7; which are evolutionarily related to GT-2 and share structure similarities.

ricin B-type lectin domain, beta-trefoil fold, found in polypeptide N-acetylgalactosaminyltransferase 7 (GALNT7) and similar proteins; GALNT7 (EC 2.4.1.41), also called polypeptide GalNAc transferase 7, GalNAc-T7, pp-GaNTase 7, protein-UDP acetylgalactosaminyltransferase 7, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 7, acts as glycopeptide transferase involved in O-linked oligosaccharide biosynthesis, which catalyzes the transfer of an N-acetyl-D-galactosamine residue to an already glycosylated peptide. In contrast to other proteins of the family, it does not act as a peptide transferase that transfers GalNAc onto serine or threonine residue on the protein receptor, but instead requires the prior addition of a GalNAc on a peptide before adding additional GalNAc moieties. Its appropriate peptide substrate remains unidentified. GALNT7 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.

ricin B-type lectin domain, beta-trefoil fold, found in Streptomyces olivaceoviridis endo-1,4-beta-xylanase and similar proteins; The family includes Streptomyces olivaceoviridis endo-1,4-beta-xylanase (XLN, EC 3.2.1.8), Streptomyces avermitilis beta-L-arabinopyranosidase (EC 3.2.1.185), and Streptomyces coelicolor extracellular exo-alpha-L-arabinofuranosidase (ABF, EC 3.2.1.55). XLN, also called xylanase, or 1,4-beta-D-xylan xylanohydrolase, belongs to the glycosyl hydrolase 10 (cellulase F) family. It contributes to hydrolyze hemicellulose, the major component of plant cell walls. XLN contains a (beta/alpha)8-barrel as a catalytic domain, a family 13 carbohydrate binding module (CBM13) as a xylan binding domain (XBD) and a Gly/Pro-rich linker between them. Beta-L-arabinopyranosidase belongs to the glycosyl hydrolase 27 (GH27) family. It has a GH27 catalytic domain, an antiparallel beta-domain containing Greek key motifs, another antiparallel beta-domain forming a jellyroll structure, and a CBM13 module. ScAraf62A, also called ABF, or arabinosidase, or arabinoxylan arabinofuranohydrolase, belongs to the glycosyl hydrolase 62 (GH62) family. It is involved in the degradation of xylan and is a key enzyme in the complete degradation of the plant cell wall. It has a specific arabinofuranose-debranching activity on xylan from gramineae. It acts synergistically with xylanases and binds specifically to xylan. ScAraf62A comprises a CBM13 module at its N-terminus and a catalytic domain at its C-terminus. This model corresponds to the CBM13 module, which is a ricin B-type lectin domain with a beta-trefoil fold, characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain may contain a potential sugar-binding pocket.

ricin B-type lectin domain, beta-trefoil fold, found in the polypeptide N-acetylgalactosaminyltransferase 14 (GALNT14)-like subfamily; The GALNT14-like subfamily includes GALNT14 and GALNT16. They act as GalNAc transferases (EC 2.4.1.41) that catalyze the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT14 displays activity toward mucin-derived peptide substrates such as Muc2, Muc5AC, Muc7, and Muc13 (-58). It may be involved in O-glycosylation in the kidney. Members of this subfamily comprise a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

Subfamily of Glycosyltransferase Family GT2 of unknown function; GT-2 includes diverse families of glycosyltransferases with a common GT-A type structural fold, which has two tightly associated beta/alpha/beta domains that tend to form a continuous central sheet of at least eight beta-strands. These are enzymes that catalyze the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds. Glycosyltransferases have been classified into more than 90 distinct sequence based families.

ricin B-type lectin domain, beta-trefoil fold, found in polypeptide N-acetylgalactosaminyltransferase 12 (GALNT12) and similar proteins; GALNT12 (EC 2.4.1.41), also called polypeptide GalNAc transferase 12, GalNAc-T12, pp-GaNTase 12, protein-UDP acetylgalactosaminyltransferase 12, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase 12, catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. GALNT12 has activity toward non-glycosylated peptides such as Muc5AC, Muc1a and EA2, and no detectable activity with non-glycosylated Muc2 and Muc7. It displays enzymatic activity toward the Gal-NAc-Muc5AC glycopeptide, but no detectable activity to mono-GalNAc-glycosylated Muc1a, Muc2, Muc7 and EA2. It may play an important role in the initial step of mucin-type oligosaccharide biosynthesis in digestive organs. GALNT12 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry.

ricin B-type lectin domain, beta-trefoil fold, found in glucan endo-1,3-beta-glucosidase and similar proteins; Glucan endo-1,3-beta-glucosidase (EC 3.2.1.39), also called (1->3)-beta-glucan endohydrolase, or (1->3)-beta-glucanase, or laminarinase, belongs to the glycosyl hydrolase 64 (GH64) family. It catalyzes hydrolysis of (1->3)-beta-D-glucosidic linkages in (1->3)-beta-D-glucans. It has been implicated in the defense against fungal pathogens. Glucan endo-1,3-beta-glucosidase contains a C-terminal ricin B-type lectin domain with a beta-trefoil fold, characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. Each subdomain bears a potential sugar binding site.

 166-254 2.26e-05

DPM_DPG-synthase_like is a member of the Glycosyltransferase 2 superfamily; DPM1 is the catalytic subunit of eukaryotic dolichol-phosphate mannose (DPM) synthase. DPM synthase is required for synthesis of the glycosylphosphatidylinositol (GPI) anchor, N-glycan precursor, protein O-mannose, and C-mannose. In higher eukaryotes,the enzyme has three subunits, DPM1, DPM2 and DPM3. DPM is synthesized from dolichol phosphate and GDP-Man on the cytosolic surface of the ER membrane by DPM synthase and then is flipped onto the luminal side and used as a donor substrate. In lower eukaryotes, such as Saccharomyces cerevisiae and Trypanosoma brucei, DPM synthase consists of a single component (Dpm1p and TbDpm1, respectively) that possesses one predicted transmembrane region near the C terminus for anchoring to the ER membrane. In contrast, the Dpm1 homologues of higher eukaryotes, namely fission yeast, fungi, and animals, have no transmembrane region, suggesting the existence of adapter molecules for membrane anchoring. This family also includes bacteria and archaea DPM1_like enzymes. However, the enzyme structure and mechanism of function are not well understood. The UDP-glucose:dolichyl-phosphate glucosyltransferase (DPG_synthase) is a transmembrane-bound enzyme of the endoplasmic reticulum involved in protein N-linked glycosylation. This enzyme catalyzes the transfer of glucose from UDP-glucose to dolichyl phosphate. This protein family belongs to Glycosyltransferase 2 superfamily.

 471-598 2.94e-05

ricin B-type lectin domain, beta-trefoil fold; The ricin B-type lectin domain is a carbohydrate-binding domain formed from presumed gene triplication. It shows a beta-trefoil fold characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain was originally found in Ricin, which is a legume lectin from the seeds of the castor bean plant, Ricinus communis. It is also found in many carbohydrate-recognition proteins like plant and bacterial AB-toxins, glycosidases, or proteases, which serve diverse functions such as inhibitory toxicity, enzymatic activity, and signal transduction. The ricin B-type lectin domain can be present in one or more copies and has been shown in some instances to bind simple sugars, such as galactose or lactose. The most characteristic, though not completely conserved, sequence feature is the presence of a Q-W pattern. Consequently, the ricin B-type lectin domain has also been referred as the (QxW)3 domain and the three homologous regions as the QxW repeats. A disulfide bond is also conserved in some QxW repeats.

ricin B-type lectin domain, beta-trefoil fold, found in polypeptide N-acetylgalactosaminyltransferase 15 (GALNT15) and similar proteins; GALNT15 (EC 2.4.1.41), also called polypeptide GalNAc transferase 15, GalNAc-T15, polypeptide GalNAc transferase-like protein 2, GalNAc-T-like protein 2, pp-GaNTase-like protein 2, polypeptide N-acetylgalactosaminyltransferase-like protein 2, protein-UDP acetylgalactosaminyltransferase-like protein 2, or UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase-like protein 2, catalyzes the initial reaction in O-linked oligosaccharide biosynthesis, the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. Although it displays a much weaker activity toward all substrates tested compared to GALNT2, GALNT15 can transfer up to seven GalNAc residues to the Muc5AC peptide, suggesting that it can fill vicinal Thr/Ser residues in cooperation with other GALNT proteins. It prefers Muc1a as its substrate. GALNT15 comprises a glycosyltransferase region and a ricin B-type lectin domain. The glycosyltransferase region contains two conserved domains, domain A (also called GT1 motif) and domain B (also called Gal/GalNAc-T motif). This model corresponds to the ricin B-type lectin domain with a beta-trefoil fold, which is characterized by 12 beta strands folded into three similar trefoil subdomains (alpha, beta, and gamma) associated to give an overall structure with pseudo-3-fold symmetry. The ricin B-type lectin domain binds to GalNAc and contributes to the glycopeptide specificity.
