Fig. 3From: Genomic insights into the thiamin metabolism of Paenibacillus thiaminolyticus NRRL B-4156 and P. apiarius NRRL B-23460Predicted thiamin biosynthesis pathway in P. apiarius NRRL 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 TPPBack to article page
