Structural interactions that enable electron transfer to cytochrome-P450 (CYP450) from its redox partner CYP450-reductase (CPR) are a vital prerequisite for its catalytic mechanism. Here, we report the first structural model for the membrane-bound functional complex to reveal interactions between the full-length CYP450 and a minimal domain of CPR. Our results suggest that anchorage of the proteins in a lipid bilayer is a minimal requirement for CYP450 catalytic function. Akin to cytochrome-b5 (cyt-b5), Arg125 on the C-helix of CYP450s is found to be important for effective electron transfer, thus supporting the competitive behavior of redox partners for CYP450s. We report a general approach to study protein-protein interactions combining the use of nanodiscs with NMR spectroscopy and SAXS. Linking structural details to the mechanism will help unravel the xenobiotic metabolism of diverse microsomal CYP450s in their native environment and facilitate the design of new drug entities. Layout 1: Solving a structure of the cytochrome P450 (CYP450) complex with its redox partner is a vital prerequisite to gaze at the selective route of electron transfer. Here we report structural interactions of CYP450-redox partner complex anchored in lipid membrane as a minimal requirement for functionality (electron transfer). This study brings about a paradigm shift to unravel the drug/xenobiotic metabolism by diverse microsomal CYPs in their native membrane environment.
