General annotation (Comments)

Function	Catalyzes C14-demethylation of lanosterol; it transforms lanosterol into 4,4'-dimethyl cholesta-8,14,24-triene-3-beta-ol.
Catalytic activity	Obtusifoliol + 3 O(2) + 3 NADPH = 4-alpha-methyl-5-alpha-ergosta-8,14,24(28)-trien-3-beta-ol + formate + 3 NADP(+) + 4 H(2)O.
Cofactor	Heme group By similarity.
Pathway	Steroid biosynthesis; zymosterol biosynthesis; zymosterol from lanosterol: step 1/6.
Subcellular location	Endoplasmic reticulum membranePotential. Microsome membranePotential.
Sequence similarities	Belongs to the cytochrome P450 family.
