direction of the regioselectivity of the enzyme towards hydroxylation at position 11 in the C ring of the steroid through a combination of saturation mutagenesis and rational site-directed mutagenesis, with aid of data from a homology model of CYP106A2 containing docked progesterone, together with site-directed mutagenesis of active site residues. Distributions of amounts of monohydroxylated progesterone products (15beta-,11alpha-, 9alpha-, and 6beta-hydroxyprogesterone) in vivo of wild-type and mutant enzymes, overview |
