Abstract In order to elucidate the biosynthesis of the base moiety of cobalamin in Salmonella typhimurium LT2, this organism was grown in the presence of [1′-14C]riboflavin. The vitamin B12 isolated was 14C-labeled. It was shown by chemical degradation that the 14C-label was exclusively localized in carbon atom 2 of the 5,6-dimethylbenzimidazole moiety. This demonstrated the precursor function of riboflavin in the biosynthesis of 5,6-dimethylbenzimidazole in S. typhimurium.
