IntEnz Enzyme Nomenclature


Accepted name:
GDP-mannose:cellobiosyl-diphosphopolyprenol α-mannosyltransferase
Other names:
α1,3-mannosyltransferase AceA
Systematic name:
GDP-mannose:D-Glc-β-(1→4)-Glc-α-1-diphosphoundecaprenol 3-α-mannosyltransferase



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].
