CC -!- FUNCTION: A cytochrome P450 monooxygenase involved in the metabolism of
CC endogenous cholesterol and its oxygenated derivatives (oxysterols)
CC (PubMed:11013305, PubMed:12077124, PubMed:19965590, PubMed:2384150,
CC PubMed:21813643). Mechanistically, uses molecular oxygen inserting one
CC oxygen atom into a substrate, and reducing the second into a water
CC molecule, with two electrons provided by NADPH via cytochrome P450
CC reductase (CPR; NADPH-ferrihemoprotein reductase) (PubMed:2384150,
CC PubMed:11013305, PubMed:12077124, PubMed:19965590, PubMed:21813643).
CC Functions as a critical regulatory enzyme of bile acid biosynthesis and
CC cholesterol homeostasis. Catalyzes the hydroxylation of carbon hydrogen
CC bond at 7-alpha position of cholesterol, a rate-limiting step in
CC cholesterol catabolism and bile acid biosynthesis (PubMed:12077124,
CC PubMed:19965590, PubMed:2384150). 7-alpha hydroxylates several
CC oxysterols, including 4beta-hydroxycholesterol and 24-
CC hydroxycholesterol (PubMed:11013305, PubMed:12077124). Catalyzes the
CC oxidation of the 7,8 double bond of 7-dehydrocholesterol and
CC lathosterol with direct and predominant formation of the 7-keto
CC derivatives (PubMed:21813643). {ECO:0000269|PubMed:11013305,
