Sumario:ABSTRACT J. Hiras, S. V. Sharma, V. Raman, R. A. J. Tinson, et al. (mBio 9:e01603-18, 2018, https://doi.org/10.1128/mBio.01603-18) report on the identification of a novel thiol, N-methyl-bacillithiol (N-Me-BSH), in the green sulfur bacterium Chlorobium tepidum. In N-methyl-bacillithiol, the amine of the cysteine is methylated by a novel S-adenosylmethioneine transferase designated N-methyl-bacillithiol synthase A (NmbA). The Hiras et al. study is significant because it is the first report of the presence of N-Me-BSH in anaerobic bacteria.
