Serine 62-68 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 28-35 9029728-14 1997 Alternatively, the affinity of P450c17 for redox partners may be selectively increased by Ser/Thr phosphorylation, or selectively decreased by certain mutations in the redox partner binding site, in either case altering an electrostatic interaction between P450c17 and the redox partner. Serine 90-93 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 31-38
