ID 2.7.8.46 DE teichoic acid ribitol-phosphate primase. AN Tar primase. CA 4-O-[(2R)-glycerylphospho]-N-acetyl-beta-D-mannosaminyl-(1->4)-N-acetyl- CA alpha-D-glucosaminyl di-trans,octa-cis-undecaprenyl diphosphate + CDP-L- CA ribitol = 4-O-[1-D-ribitylphospho-(2R)-1-glycerylphospho]-N-acetyl-beta- CA D-mannosaminyl-(1->4)-N-acetyl-alpha-D-glucosaminyl di-trans,octa- CA cis-undecaprenyl diphosphate + CMP + H(+). CC -!- Involved in the biosynthesis of teichoic acid linkage units in the CC cell wall of Bacillus subtilis W23. CC -!- This enzyme adds the first ribitol unit to the disaccharide linker of CC the teichoic acid. DR Q8RKJ1, TARK_BACSH ; //
