56-dimethylbenzimidazole synthase (EC 1.14.99.40 BluB) is an enzyme with system name FMNH2 oxidoreductase (56-dimethylbenzimidazole forming). This enzyme catalyses the following chemical reaction FMNH2 + NADH + H+ + O2 56-dimethylbenzimidazole + D-erythrose 4-phosphate + NAD+ + other productThe C-2 of 56-dimethylbenzimidazole is derived from C-1′ of the ribityl group of FMNH2 and 2-H from the ribityl 1′-pro-S hydrogen.
