Protein attributes

Sequence length	466 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalyzes C14-demethylation of lanosterol which is critical for ergosterol biosynthesis. It transforms lanosterol into 4,4'-dimethyl cholesta-8,14,24-triene-3-beta-ol By similarity.
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 metabolism; zymosterol biosynthesis; zymosterol from lanosterol: step 1/6.
Subcellular location	MembranePotential. Membrane; Single-pass membrane protein.
Sequence similarities	Belongs to the cytochrome P450 family.
