Methyltransferase/kinase WbdD (original) (raw)

Methyltransferase/kinase WbdD EC 2.1.1.294 and EC 2.7.1.181 WbdD is a bifunctional enzyme that regulates the length of the LPS O-antigen polysaccharide chain. Stops the polymerization of the chain by phosphorylating and then methylating the phosphate on the terminal sugar. This terminal modification is essential for export of the O-antigen across the inner membrane. WbdD is also required for correct localization of the WbdA mannosyltransferase. This protein is involved in the pathway LPS O-antigen biosynthesis, which is part of Bacterial outer membrane biogenesis. Catalytic activities:
