Sterol-C4-methyl oxidase-like [Homo sapiens]

Protein Classification

sterol desaturase family protein( domain architecture ID 10513792)

sterol desaturase family protein is an oxidoreductase, similar to C-5 sterol desaturase, which catalyzes a dehydrogenation reaction to introduce a C5-6 double bond into substrates such as lathosterol and the B ring of ergosterol

Fatty acid hydroxylase; This entry includes fatty acid and carotene hydroxylases and sterol desaturases. Beta-carotene hydroxylase is involved in zeaxanthin synthesis by hydroxylating beta-carotene, but the enzyme may be involved in other pathways. This family includes C-5 sterol desaturase and C-4 sterol methyl oxidase. Members of this family are involved in cholesterol biosynthesis and biosynthesis a plant cuticular wax. These enzymes contain two copies of a HXHH motif which coordinate two irons at the catalytic centre. Members of this family are ER integral membrane proteins that share a novel mushroom-shaped fold consisting of four transmembrane (TM1-TM4) helices that anchor them to the membrane capped by a cytosolic domain containing the unique histidine- coordinating di metal centre.
