Comments
Comment typeDescription
FunctionMembrane bound hemoprotein which function as an electron carrier for several membrane bound oxygenases. It plays a role in fatty-acid desaturation and is also involved in several steps of the sterol biosynthesis pathway, particularly in the 4- demethylation of the 4,4'-dimethyl zymosterol.
