ID 2.4.99.27 DE O-antigen polymerase Wzy. AN Wzy O-antigen polymerase. AN Wzy polymerase. CA n lipid-linked O-antigen repeat units = a lipid-linked O antigen + (n-1) CA polyisoprenyl diphosphate. CC -!- The Wzy-type polymerase polymerizes O antigen repeat unit CC oligosaccharides that are anchored to the periplasmic face of the CC inner membrane, forming an O antigen polysaccharide that is still CC anchored to the membrane. CC -!- A Wzz chain length regulator (sometimes referred to as an O-antigen CC co-polymerase) normally interacts with Wzy to confer a distinctive CC modal chain length distribution. CC -!- The resultant polysaccharide is transferred from the membrane anchor CC to the lipid A-core oligosaccharide by EC 2.4.99.26 forming a CC complete lipopolysaccharide structure. CC -!- There is an enormous diversity of O antigen polymerases with CC different specificities, reflecting the variability in the structure CC and composition of O-antigens.
