The coenzyme B₁₂ precursor 5,6-dimethylbenzimidazole is a flavin antagonist in Salmonella

August 17, 2023

Here we investigated why 5,6-dimethylbenzimidazole (DMB) inhibits in S. Typhimurium. Briefly, we determined that the structural similarities of the substituted benzene ring of DMB with the isoalloxazine moiety of flavins is responsible for the deleterious effects of this CoB12 precursor.
