Structure of the open conformation of a functional chimeric NADPH cytochrome P450 reductase
Open accessAbstract
Two catalytic domains, bearing FMN and FAD cofactors, joined by a connecting domain, compose the core of the NADPH cytochrome P450 reductase (CPR). The FMN domain of CPR mediates electron shuttling from the FAD domain to cytochromes P450. Together, both enzymes form the main mixed-function oxidase system that participates in the metabolism of endo- and xenobiotic compounds in mammals. Available CPR structures show a closed conformation, with the two cofactors in tight proximity, which is consistent with FAD-to-FMN, but not FMN-to-P450, electron transfer. Here, we report the 2.5 A resolution crystal structure of a functionally competent yeast-human chimeric CPR in an open conformation, compatible with FMN-to-P450 electron transfer. Comparison with closed structures shows a major conformational change separating the FMN and FAD cofactors from 86 A.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
