Xanthomonas campestris

-

EDTA-treated Xanthomonas campestris cells are used as both enzyme preparation and lipid-P acceptor, and UDP-Glc, GDP-Man, and UDP-glucuronic acid are used as sugar donors. A linear pentasaccharide unit is assembled on a polyprenol-P lipid carrier by the sequential addition of glucose-1-P, glucose, mannose, glucuronic acid, and mannose

Xanthomonas oryzae

-

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
