reduction of both NAD+ and Fd by Nfn enzymes is coupled to the bifurcation of electrons from NADPH oxidation. The exergonic coupling of the NADP(H) and NAD(H) half reactions in Nfn is presumed to be mediated by NADPH oxidation at L-FAD followed by electron transfer to the proximal [2Fe-2S] cluster and subsequently the NAD(H) binding site at S-FAD. Biophysical analysis of the enzyme provides the first direct insight into the mechanism of flavin-based electron bifurcation and the requisite structural features
