Function |
This enzyme is involved in the metabolism of various endogenous substrates, including fatty acids, steroid hormones and vitamins. It catalyzes the hydroxylation of carbon-hydrogen bonds and exhibits high catalytic activity for the formation of hydroxyestrogens from estrone (E1) and 17beta-estradiol (E2), namely 2-hydroxy E1 and E2, as well as D-ring hydroxylated E1 and E2 at the C15-alpha and C16- alpha positions. It also displays different regioselectivities for polyunsaturated fatty acids (PUFA) hydroxylation and Catalyzes the epoxidation of double bonds of certain PUFA.
