Progesterone 24-36 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 71-77 9667077-6 1998 CYP3A4 showed the highest progesterone 16 alpha-hydroxylation activity, followed by CYP1A1 and CYP2D6. Progesterone 26-38 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 0-6 9667077-10 1998 Addition of nifedipine, a typical substrate of CYP3A4, inhibited the 6 beta- and 16 alpha-hydroxylation of progesterone by CYP3A4. Progesterone 107-119 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 47-53 9667077-10 1998 Addition of nifedipine, a typical substrate of CYP3A4, inhibited the 6 beta- and 16 alpha-hydroxylation of progesterone by CYP3A4. Progesterone 107-119 cytochrome P450 family 3 subfamily A member 4 Homo sapiens 123-129
