GumM is involved in biosynthesis of the pentasaccharide repeating unit of xanthan. It is suggested that the wild-type Xanthomonas oryzae-produced xanthan is assembled by the sequential addition of UDP-glucose, UDP-glucose, GDP-mannose, UDP-glucuronic acid, and GDP-mannose onto a polyprenol phosphate carrier, by the glycosyltransferase homologues encoded by the gumD, gumM, gumH, gumK, and gumI genes, respectively
