A 1.9-A molecular structure of the microsomal cytochrome P450 2B4 with the specific inhibitor 4-(4-chlorophenyl)imidazole (CPI) in the active site was determined by x-ray crystallography. In contrast to the previous experimentally determined 2B4 structure, this complex adopted a closed conformation similar to that observed for the mammalian 2C enzymes. The differences between the open and closed structures of 2B4 were primarily limited to the lid domain of helices F through G, helices B' and C… CONTINUE READING
