EC 2.7.8.46     
Accepted name: teichoic acid ribitol-phosphate primase
Reaction: CDP-ribitol + 4-O-[(2R)-1-glycerophospho]-N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol = CMP + 4-O-[1-D-ribitylphospho-(2R)-1-glycerophospho]-N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol
Other name(s): Tar primase; tarK (gene name)
Systematic name: CDP-ribitol:4-O-[(2R)-1-glycerophospho]-N-acetyl-β-D-mannosaminyl-(1→4)-N-acetyl-α-D-glucosaminyl-diphospho-ditrans,octacis-undecaprenol ribitylphosphotransferase
Comments: Involved in the biosynthesis of teichoic acid linkage units in the cell wall of Bacillus subtilis W23. This enzyme adds the first ribitol unit to the disaccharide linker of the teichoic acid.
