General annotation (Comments)

Function	Catalyzes the first step in the oxidation of the side chain of sterol intermediates; the 27-hydroxylation of 5-beta-cholestane-3-alpha,7-alpha,12-alpha-triol. Has also a vitamin D3-25-hydroxylase activity By similarity.
Catalytic activity	5-beta-cholestane-3-alpha,7-alpha,12-alpha-triol + NADPH + O2 = (25R)-5-beta-cholestane-3-alpha,7-alpha,12-alpha,26-tetraol + NADP+ + H2O.
Cofactor	Heme group By similarity.
Pathway	Hormone biosynthesis; cholecalciferol biosynthesis.
Subcellular location	Mitochondrion membrane By similarity.
Post-translational modification	Acetylation of Lys-125 and Lys-285 is observed in liver mitochondria from fasted mice but not from fed mice.
Sequence similarities	Belongs to the cytochrome P450 family.
