Reaction: CDP-glycerol + N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol = CDP + 4-O-[(2R)-1-glycerophospho]-N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol
Other name(s): Tag primase; CDP-glycerol:glycerophosphate glycerophosphotransferase; tagB (gene name); tarB (gene name)
Systematic name: CDP-glycerol:N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol glycerophosphotransferase
Comments: Involved in the biosynthesis of teichoic acid linkage units in bacterial cell walls. This enzyme adds the first glycerol unit to the disaccharide linker of the teichoic acid.
