The rates of reaction of 5-ethyl-3-methyllumiflavinium perchlorate and 5-ethyl-3-methyllumiflavinyl radical with a NADH analogue, N-benzyl-1,4-dihydronicotinamide, were measured anaerobically in tert-butanol and 5% acetonitrile/95% tert-butanol solutions at 30 degrees C. The biphasic kinetics observed for the reaction of flavin radical with dihydronicotinamide were interpreted in terms of both a 1e- and a 2e- mechanism; the former was found to be inadequate based on experimental requirements of the mechanism. The dihydronicotinamide reacts preferentially with oxidized flavin rather than flavin radical, even when the concentration of oxidized flavin is at a concentration 5 orders of magnitude less than that of radical. These studies show that the "hydride" reduction of oxidized flavin by BNAH is more facile than is the 1e- reduction of flavin radical by BNAH.
