The members of this subfamily catalyze the formation of a phosphodiester bond between a membrane-associated undecaprenyl-phosphate (Und-P) molecule and N-acetylhexosamine 1-phosphate, which is usually donated by a soluble UDP-N-acetylhexosamine precursor. The WbcO/WbpL substrate specificity has not yet been determined, but the structure of their biosynthetic end products implies that UDP-N-acetyl-D-fucosamine (UDP-FucNAc) and/or UDPN-acetyl-D-quinosamine (UDP-QuiNAc) are used. The subgroup of bacterial UDP-HexNAc:polyprenol-P HexNAc-1-P transferases includes the WbcO protein from Yersinia enterocolitica and the WbpL protein from Pseudomonas aeruginosa. These transferases initiate LPS O-antigen biosynthesis. Similar to other GlcNAc/MurNAc-1-P transferase family members, WbpL is a highly hydrophobic protein possessing 11 predicted transmembrane segments. : Pssm-ID: 133464 Cd Length: 253 Bit Score: 214.80 E-value: 1.22e-68

This subfamily contains Escherichia coli WecA, Bacillus subtilis TagO and related proteins. WecA is an UDP-N-acetylglucosamine (GlcNAc):undecaprenyl-phosphate (Und-P) GlcNAc-1-phosphate transferase that catalyzes the formation of a phosphodiester bond between a membrane-associated undecaprenyl-phosphate molecule and N-acetylglucosamine 1-phosphate, which is usually donated by a soluble UDP-N-acetylglucosamine precursor. WecA participates in the biosynthesis of O antigen LPS in many enteric bacteria and is also involved in the biosynthesis of enterobacterial common antigen. A conserved short sequence motif and a conserved arginine at a cytosolic loop of this integral membrane protein were shown to be critical in recognition of substrate UDP-N-acetylglucosamine.

This subfamily is composed of uncharacterized bacterial glycosyltransferases in the MraY-like family. This family contains both eukaryotic and prokaryotic UDP-D-N-acetylhexosamine:polyprenol phosphate D-N-acetylhexosamine-1-phosphate transferases, which catalyze the transfer of a D-N-acetylhexosamine 1-phosphate to a membrane-bound polyprenol phosphate. This is the initiation step of protein N-glycosylation in eukaryotes and peptidoglycan biosynthesis in bacteria. The three bacterial members MraY, WecA, and WbpL/WbcO, utilize undecaprenol phosphate as the acceptor substrate, but use different UDP-sugar donor substrates. MraY-type transferases are highly specific for UDP-N-acetylmuramate-pentapeptide, whereas WecA proteins are selective for UDP-N-acetylglucosamine (UDP-GlcNAc). The WbcO/WbpL substrate specificity has not yet been determined, but the structure of their biosynthetic end products implies that UDP-N-acetyl-D-fucosamine (UDP-FucNAc) and/or UDPN-acetyl-D-quinosamine (UDP-QuiNAc) are used. The prokaryotic enzyme-catalyzed reactions lead to the formation of polyprenol-linked oligosaccharides involved in bacterial cell wall and peptidoglycan assembly.

Phospho-N-acetylmuramoyl-pentapeptide-transferase (mraY) is an enzyme responsible for the formation of the first lipid intermediate in the synthesis of bacterial cell wall peptidoglycan. It catalyzes the formation of undecaprenyl-pyrophosphoryl-N-acetylmuramoyl-pentapeptide from UDP-MurNAc-pentapeptide and undecaprenyl-phosphate. It is an integral membrane protein with possibly ten transmembrane domains. Pssm-ID: 133462 Cd Length: 280 Bit Score: 54.42 E-value: 1.88e-08

UDP-GlcNAc:dolichol-P GlcNAc-1-P transferase (GPT)-like proteins in archaea. Eukaryotic GPT catalyzes the transfer of GlcNAc-1-P from UDP-GlcNAc to dolichol-P to form GlcNAc-P-P-dolichol. The reaction is the first step in the assembly of dolichol-linked oligosaccharide intermediates and is essential for eukaryotic N-linked glycosylation. Evidence for the existence of the N-glycosylation pathway in archaea has emerged and genes responsible for the pathway have been identified. A glycosyl transferase gene Mv1751 in M. voltae encodes for the enzyme that carries out the first step in the pathway, the attachment of GlcNAc to a dolichol lipid carrier in the membrane. A lethal mutation in the alg7 (GPT) gene in Saccharomyces cerevisiae was successfully complemented with Mv1751, the archaea gene, indicating that eukaryotic and archaeal enzymes may use the same substrates and are evolutionarily closer than the bacterial enzyme, which uses a different substrate.

Glycosyltransferase 4 (GT4) includes both eukaryotic and prokaryotic UDP-D-N-acetylhexosamine:polyprenol phosphate D-N-acetylhexosamine-1-phosphate transferases. They catalyze the transfer of a D-N-acetylhexosamine 1-phosphate to a membrane-bound polyprenol phosphate, which is the initiation step of protein N-glycosylation in eukaryotes and peptidoglycan biosynthesis in bacteria. One member, D-N-acetylhexosamine 1-phosphate transferase (GPT) is a eukaryotic enzyme, which is specific for UDP-GlcNAc as donor substrate and dolichol-phosphate as the membrane bound acceptor. The bacterial members MraY, WecA, and WbpL/WbcO utilize undecaprenol phosphate as the acceptor substrate, but use different UDP-sugar donor substrates. MraY-type transferases are highly specific for UDP-N-acetylmuramate-pentapeptide, whereas WecA proteins are selective for UDP-N-acetylglucosamine (UDP-GlcNAc). The WbcO/WbpL substrate specificity has not yet been determined, but the structure of their biosynthetic endproducts implies that UDP-N-acetyl-D-fucosamine (UDP-FucNAc) and/or UDPN-acetyl-D-quinosamine (UDP-QuiNAc) are used. The eukaryotic reaction is the first step in the assembly of dolichol-linked oligosaccharide intermediates and is essential for N-glycosylation. The prokaryotic reactions lead to the formation of polyprenol-linked oligosaccharides involved in bacterial cell wall and peptidoglycan assembly. Archaeal and eukaryotic enzymes may use the same substrates and are evolutionarily closer than the bacterial enzyme. Archaea possess the same N-glycosylation pathway as eukaryotes. A glycosyl transferase gene Mv1751 in M. voltae encodes for the enzyme that carries out the first step in the pathway, the attachment of GlcNAc to a dolichol lipid carrier in the membrane. A lethal mutation in the alg7 (GPT) gene in Saccharomyces cerevisiae was successfully complemented with Mv1751, the archaea gene. Pssm-ID: 133460 Cd Length: 185 Bit Score: 44.60 E-value: 1.63e-05
