Oxysterols 217-226 cytochrome P450 family 7 subfamily A member 1 Sus scrofa 30-61 7925343-9 1994 It has been suggested that cholesterol 7 alpha-hydroxylase can preferentially use oxysterols, in particular 25-hydroxycholesterol, as substrates and by this means inactivate important physiological regulators of cholesterol homeostasis. Oxysterols 82-92 cytochrome P450 family 7 subfamily A member 1 Sus scrofa 27-58 10882719-7 2000 A partially purified and reconstituted cholesterol 7 alpha-hydroxylase enzyme fraction from pig liver showed 7 alpha-hydroxylase activity toward the same oxysterols as metabolized by expressed recombinant human and rat CYP7A. Oxysterols 154-164 cytochrome P450 family 7 subfamily A member 1 Sus scrofa 39-70
