2.7.8.12

Accepted name:

teichoic acid poly(glycerol phosphate) polymerase

Reaction:

n CDP-glycerol + 4-O-[(2R)-glycerophospho]-N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol = n CMP + 4-O-{poly[(2R)-glycerophospho]-(2R)-glycerophospho}-N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol

Other name(s):

teichoic-acid synthase; cytidine diphosphoglycerol glycerophosphotransferase; poly(glycerol phosphate) polymerase; teichoic acid glycerol transferase; glycerophosphate synthetase; CGPTase; CDP-glycerol glycerophosphotransferase (ambiguous); Tag polymerase; CDP-glycerol:poly(glycerophosphate) glycerophosphotransferase; tagF (gene name); tarF (gene name) (ambiguous)

Systematic name:

CDP-glycerol:4-O-[(2R)-glycerophospho]-N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol glycerophosphotransferase

Comments:

Involved in the biosynthesis of poly glycerol phosphate teichoic acids in bacterial cell walls. This enzyme adds 30–50 glycerol units to the linker molecule, but only after it has been primed with the first glycerol unit by EC 2.7.8.44, teichoic acid poly(glycerol phosphate) primase. cf. EC 2.7.8.45, teichoic acid glycerol-phosphate transferase.
