intrigued by the apparent requirement of dithionite for fmn reduction ( as opposed to photoreduction or catalytic hydrogenation ) in the h2o2-initiated bacterial bioluminescence reaction , we chose 5-ethyl-3-methyllumiflavinium cation i as a model to investigate possible flavin adduct formation by treatment with dithionite or ( bi ) sulfite .
