Nameexopolysaccharide biosynthesis, exosortase A-associated
TypeSYSTEM
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.
