We have recently cloned a full-length cDNA encoding the rat hepatic cholesterol 7 alpha-hydroxylase cytochrome P450 (P450c7) (Li, Y. C., Wang, D. P., and Chiang, J. Y. L. (1990) J. Biol. Chem. 265, 12012-12019), which catalyzes the rate-limiting…
Oxysterol 7alpha-hydroxylase has broad substrate specificity for sterol metabolites and may be involved in many metabolic processes including bile acid synthesis and neurosteroid metabolism. The cloned human oxysterol 7alpha-hydroxylase (CYP7B1) cDNA…
