Heme oxygenase (HO) catalyzes heme degradation using electrons supplied by NADPH-cytochrome P450 oxidoreductase (CPR). Electrons from NADPH flow first to FAD, then to FMN, and finally to the heme in the redox partner. Previous biophysical analyses suggest the presence of a dynamic equilibrium betwee...
