ENZYME entry: EC 2.5.1.95

Accepted Name
Xanthan pyruvate transferase.
Reaction catalysed
Phosphoenolpyruvate + D-Man-beta-(1->4)-D-GlcA-beta-(1->2)-D-Man-alpha-(1->3)-D-Glc-beta-(1->4)-D-Glc-alpha-1-diphospho-ditrans,octacis-undecaprenol <=> 4,6-CH3(COO(-))C-D-Man-beta-(1->4)-D-GlcA-beta-(1->2)-D-Man-alpha-(1->3)-D-Glc-beta-(1->4)-D-Glc-alpha-1-diphospho-ditrans,octacis-undecaprenol + phosphate
Comment(s)
  • Involved in the biosynthesis of the polysaccharide xanthan.
  • 30-40% of terminal mannose residues of xanthan have a 4,6-O- (1-carboxyethan-1,1-diyl) ketal group.
  • It also acts on the 6-O-acetyl derivative of the inner mannose unit.
