Nameexopolysaccharide biosynthesis, exosortase B-associated
DescriptionAt least 30 different bacterial species known so far have the PEP-CTERM/exosortase system believed to process proteins analogously to the LPXTG/sortase system. Genes associated with this processing are found among exopolysaccharide biosynthesis genes, suggesting that PEP-CTERM proteins are part of this exopolysaccharide system, and therefore are likely to be transported across the outer membrane. This property represents a panel of exopolysaccharide biosynthesis genes where each belongs to a subfamily that marks its host gene as carrying the PEP-CTERM/exopolysaccharide system. This type 2 version of the system is found in Methylobacillus sp. strain 12S where it is embedded in a region for the biosynthesis of the exopolysaccharide mthanolan.
