Predicted thiamin biosynthesis pathway in 10.1601/nm.5116 10.1601/strainfinder?urlappend=%3Fid%3DNRRL+B-23460. Pathways involved in thiazole biosynthesis are highlighted in blue and pathways involved in pyrimidine biosynthesis are shown in red. The steps in black correspond to the coupling of the thiazole and pyrimidine moieties, and the formation of the active cofactor TPP
