1. It has been shown that redox equilibria can be formed between dithionite ion (plus SO-2) and (bi)sulphite, and the low-potential electron carriers flavodoxin and methyl viologen. The equilibria were established either by treating the oxidized electron carriers with dithionite, or by treating flavodoxin hydroquinone or methyl viologen semiquinone with (bi)sulphite. Similar redox equilibria were established between dithionite/(bi)sulphite and hydrogen using catalytic amounts of hydrogenase in… CONTINUE READING
