Protein Domain : Sugar transferase, PEP-CTERM system associated IPR017464

Type	Family
Description	Members of this protein family belong to the family of bacterial sugar transferases ( ). 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. (strain MC-1) and Myxococcus xanthus (strain 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 catalysed by members of this clade is unknown and may conceivably be variable with respect to substrate by species. These proteins are homologues of the EpsB protein found in Methylobacillus sp. 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 characterised enterobacterial homologues, and is considerably more specific than warranted from the currently available evidence.
