The Molecular Cannibal in Vitamin B12 Synthesis An enzyme called BluB single-handedly carries out an act of 'molecular cannibalism', pulling apart vitamin B 2 (riboflavin) to produce a key component of vitamin B 12 known as 5,6-dimethylbenzimidazole (DMB). This fills a glaring gap in our understanding of the biosynthesis of the vitamin. |
