<span class="mw-page-title-main">Methyltransferase/kinase WbdD</span>

Methyltransferase/kinase WbdD EC 2.1.1.294 and EC 2.7.1.181WbdD 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.
