2.4.1.355
Accepted name
poly(ribitol-phosphate) β-N-acetylglucosaminyltransferase
Reaction
n UDP-N-acetyl-α-D-glucosamine + 4-O-(D-ribitylphospho)n-di[(2R)-1-glycerophospho]-N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol = n UDP + 4-O-(2-N-acetyl-β-D-glucosaminyl-D-ribitylphospho)n-di[(2R)-1-glycerophospho]-N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol
Other name(s)

Systematic name
UDP-N-acetyl-α-D-glucosamine:4-O-(D-ribitylphospho)n-di[(2R)-1-glycerophospho]-N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol β-N-acetyl-D-glucosaminyltransferase (configuration-inverting)
Comment
Involved in the biosynthesis of poly(ribitol-phosphate) teichoic acids in the cell wall of the bacterium Staphylococcus aureus. This enzyme adds an N-acetyl-β-D-glucosamine to the OH group at the 2 position of the ribitol phosphate units. cf. EC 2.4.1.70 [poly(ribitol-phosphate) α-N-acetylglucosaminyltransferase].
