A model for controlling redox reactivities of flavins by conformational changes between oxidized and reduced states
Abstract
The 9,10-ethylene linked flavin (1) is more reactive than the 9, 10-trimethylene linked flavin (2) for oxidation (Fox.→ FH2), and less reactive to reduction[FH2→ Fox. and FH2→·FM (metal-chelated flavin radical)], evidence that ·FM contains an almost planar flavin moiety.
