Structures of the ferric NO complex of P450nor obtained by a SF-ROX and b, c synchrotron X-ray crystallography. The X-ray doses in the synchrotron data collection were b 0.72 and c 5.7 MGy. The 2F o−F c maps are shown in gray and contoured at 1.2σ, and the F o−F c positive maps are shown in turquoise and contoured at 7.0σ. All data were taken at 100 K in the absence of NADH
