CC -!- FUNCTION: A cytochrome P450 monooxygenase involved in corticoid and
CC androgen biosynthesis. Catalyzes 17-alpha hydroxylation of C21
CC steroids, which is common for both pathways. A second oxidative step,
CC required only for androgen synthesis, involves an acyl-carbon cleavage.
CC The 17-alpha hydroxy intermediates, as part of adrenal glucocorticoids
CC biosynthesis pathway, are precursors of cortisol. Hydroxylates steroid
CC hormones, pregnenolone and progesterone to form 17-alpha hydroxy
CC metabolites, followed by the cleavage of the C17-C20 bond to form C19
CC steroids, dehydroepiandrosterone (DHEA) and androstenedione. Has 16-
CC alpha hydroxylase activity. Catalyzes 16-alpha hydroxylation of 17-
CC alpha hydroxy pregnenolone, followed by the cleavage of the C17-C20
CC bond to form 16-alpha-hydroxy DHEA. Also 16-alpha hydroxylates
CC androgens, relevant for estriol synthesis. Mechanistically, uses
CC molecular oxygen inserting one oxygen atom into a substrate, and
CC reducing the second into a water molecule, with two electrons provided
CC by NADPH via cytochrome P450 reductase (CPR; NADPH-ferrihemoprotein
CC reductase). {ECO:0000250|UniProtKB:P05093}.
