Reaction

GDP-mannose + D-Glc-β-(1→4)-Glc-α-1-diphospho-ditrans,octacis-undecaprenol = GDP + D-Man-α-(1→3)-D-Glc-β-(1→4)-D-Glc-α-1-diphospho-ditrans,octacis-undecaprenol

Other name(s)

GumH, AceA, α1,3-mannosyltransferase AceA

Systematic name

GDP-mannose:D-Glc-β-(1→4)-Glc-α-1-diphospho-ditrans,octacis-undecaprenol 3-α-mannosyltransferase

Comment

In the bacterium Gluconacetobacter xylinus (previously known as Acetobacter xylinum) the enzyme is involved in the biosynthesis of the exopolysaccharide acetan [1]. In Xanthomonas campestris the enzyme is involved in the biosynthesis of the exopolysaccharide xanthan [5].
