fatty acid 2-hydroxylase isoform X1 [Homo sapiens]

Protein Classification

fatty acid 2-hydroxylase( domain architecture ID 10445814)

fatty acid 2-hydroxylase is an integral membrane involved in processes such as cholesterol biosynthesis or biosynthesis of plant cuticular wax. It catalyzes the hydroxylation of free fatty acids at the C-2 position to produce 2-hydroxy fatty acids, which are building blocks of sphingolipids and glycosphingolipids, for example, and contains an N-terminal cytochrome b5-like heme/steroid binding domain

 124-263 8.16e-41

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.

Cytochrome b5-like Heme/Steroid binding domain; This family includes heme binding domains from a diverse range of proteins. This family also includes proteins that bind to steroids. The family includes progesterone receptors. Many members of this subfamily are membrane anchored by an N-terminal transmembrane alpha helix. This family also includes a domain in some chitin synthases. There is no known ligand for this domain in the chitin synthases.
