4-Cholesten-7alpha,24(S)-diol-3-one, NADPH + H+, and O2 form 4-cholesten-7-alpha,12-alpha,24(S)-triol-3-one + NADP+ + H2O. This reaction is catalyzed by sterol 12alpha hydroxylase (CYP8B1), an enzyme associated with the endoplasmic reticulum membrane. While the human gene has been cloned (Gafvels et al. 1999), its protein product has not been characterized, and the enzymatic properties of human CYP8B1 protein are inferred from those of its well-characterized rabbit homolog (Ishida et al. 1992).
