Possible inhibitory effect of teichoic acid on Bacillus subtilis transfer ribonucleic acid

[摘要]

1. tRNA of Bacillus subtilis was found to be variably contaminated with membrane teichoic acid. 2. Samples with high contents of teichoic acid showed no accepting activity for tRNA^Phe and tRNA^Tyr. 3. Removal of teichoic acid restored accepting activity and fractions containing teichoic acid, separated on Sephadex G-150, inhibited the charging of tRNA^Tyr. 4. The presence of teichoic acid did not inhibit the charging of tRNA^His.
