Heme oxygenase (HO) is the major enzyme involved in heme degradation utilizing the redox equivalents supplied from NADPH-cytochrome P450 reductase (CPR). In this study, we found that the mutated CPR (ΔTGEE) is strongly interacted with heme-HO complex. We could determine the crystal structure of ΔTGEE-heme-HO complex at 4.3Å resolution. Based on the structure, the mechanism of the electron transfer from CPR to heme-HO complex accompanied with the large domain motion of CPR has been proposed. The proposed mechanism of the electron transfer was supported by the results from small-angle X-ray scattering, cross-linking, and ultra-centrifuge techniques.
