Synthesis of teichoic acid by Bacillus subtilis protoplasts.

Protoplasts of Bacillus subtilis W23 readily synthesized ribitol teichoic acid from nucleotide precursors in the surrounding medium. With cytidine diphosphate-ribitol they made poly(ribitol phosphate), presumably attached to lipoteichoic acid carrier; when cytidine diphosphate-glycerol and uridine diphosphate-N-acetylglucosamine were also present a 10-fold increase in the rate of polymer synthesis occurred, and the product contained both the main chain and the linkage unit. Synthesis was inhibited by trypsin or p-chloromercuribenzenesulfonate in the medium, and we concluded that it occurred at the outer surface of the membrane. During synthesis, which was also achieved readily by whole cells after a brief period of wall lysis, the cytidine phosphate portion of the nucleotide precursors did not pass through the membrane. No evidence could be obtained for a transphosphorylation mechanism for the translocation process. It is suggested that reaction with exogenous substrates was due to temporary exposure of a protein component of the enzyme complex at the outer surface of the membrane during the normal biosynthetic cycle.[1]
