Undecaprenyl-phosphate glucose phosphotransferase; This family of proteins encompasses the E. coli WcaJ protein involved in colanic acid biosynthesis, the Methylobacillus EpsB protein involved in methanolan biosynthesis, as well as the GumD protein involved in the biosynthesis of xanthan. All of these are closely related to the well-characterized WbaP (formerly RfbP) protein, which is the first enzyme in O-antigen biosynthesis in Salmonella typhimurium. The enzyme transfers galactose from UDP-galactose (NOTE: not glucose) to a polyprenyl carrier (utilizing the highly conserved C-terminal sugar transferase domain, pfam02397) a reaction which takes place at the cytoplasmic face of the inner membrane. The N-terminal hydrophobic domain is then believed to facilitate the "flippase" function of transferring the liposaccharide unit from the cytoplasmic face to the periplasmic face of the inner membrane. Most of these genes are found within large operons dedicated to the production of complex exopolysaccharides such as the enterobacterial O-antigen. Colanic acid biosynthesis utilizes a glucose-undecaprenyl carrier, knockout of EpsB abolishes incorporation of UDP-glucose into the lipid phase, and the C-terminal portion of GumD has been shown to be responsible for the glucosyl-1-transferase activity.

1-157 | 4.87e-103 | ||||
exopolysaccharide biosynthesis polyprenyl glycosylphosphotransferase; Members of this family are generally found near other genes involved in the biosynthesis of a variety of exopolysaccharides. These proteins consist of two fused domains, an N-terminal hydrophobic domain of generally low conservation and a highly conserved C-terminal sugar transferase domain (pfam02397). Characterized and partially characterized members of this subfamily include Salmonella WbaP (originally RfbP), E. coli WcaJ, Methylobacillus EpsB, Xanthomonas GumD, Vibrio CpsA, Erwinia AmsG, Group B Streptococcus CpsE (originally CpsD), and Streptococcus suis Cps2E. Each of these is believed to act in transferring the sugar from, for instance, UDP-glucose or UDP-galactose, to a lipid carrier such as undecaprenyl phosphate as the first (priming) step in the synthesis of an oligosaccharide "block". This function is encoded in the C-terminal domain. The liposaccharide is believed to be subsequently transferred through a "flippase" function from the cytoplasmic to the periplasmic face of the inner membrane by the N-terminal domain. Certain closely related transferase enzymes, such as Sinorhizobium ExoY and Lactococcus EpsD, lack the N-terminal domain and are not found by this model.

Undecaprenyl-phosphate galactose phosphotransferase, WbaP; The WbaP (formerly RfbP) protein has been characterized as the first enzyme in O-antigen biosynthesis in Salmonella typhimurium. The enzyme transfers galactose from UDP-galactose to a polyprenyl carrier (utilizing the highly conserved C-terminal sugar transferase domain, pfam02397) a reaction which takes place at the cytoplasmic face of the inner membrane. The N-terminal hydrophobic domain is then believed to facilitate the "flippase" function of transferring the liposaccharide unit from the cytoplasmic face to the periplasmic face of the inner membrane. This model includes the enterobacterial enzymes, where the function is presumed to be identical to the S. typhimurium enzyme as well as a somewhat broader group which are likely to catalyze the same or highly similar reactions based on a phylogenetic tree-building analysis of the broader sugar transferase family. Most of these genes are found within large operons dedicated to the production of complex exopolysaccharides such as the enterobacterial O-antigen. The most likely heterogeneity would be in the precise nature of the sugar molecule transferred. Pssm-ID: 274395 [Multi-domain] Cd Length: 456 Bit Score: 152.13 E-value: 1.02e-44

1-147 | 1.41e-43 | ||||
sugar transferase, PEP-CTERM system associated; Members of this protein family belong to the family of bacterial sugar transferases (pfam02397). Nearly all are found in species that encode the PEP-CTERM/exosortase system predicted to act in protein sorting in a number of Gram-negative bacteria (notable exceptions appear to include Magnetococcus sp. MC-1 and Myxococcus xanthus DK 1622 ). These genes are generally found near one or more of the PrsK, PrsR or PrsT genes that have been related to the PEP-CTERM system by phylogenetic profiling methods. The nature of the sugar transferase reaction catalyzed by members of this clade is unknown and may conceivably be variable with respect to substrate by species. These proteins are homologs of the EpsB protein found in Methylobacillus sp. strain 12S, which is also associated with a PEP-CTERM system, but of a distinct type. A name which appears attached to a number of genes (by transitive annotation) in this family is "undecaprenyl-phosphate galactose phosphotransferase", which comes from relatively distant characterized enterobacterial homologs, and is considerably more specific than warranted from the currently available evidence.
