IUBMB Enzyme Nomenclature


Accepted name: long-chain acyl-CoA ω-monooxygenase

Reaction: (1) oleoyl-CoA + [reduced NADPH—hemoprotein reductase] + O2 = 18-hydroxyoleoyl-CoA + [oxidized NADPH—hemoprotein reductase] + H2O
(2) linoleoyl-CoA + [reduced NADPH—hemoprotein reductase] + O2 = 18-hydroxylinoleoyl-CoA + [oxidized NADPH—hemoprotein reductase] + H2O

Other name(s): long-chain acyl-CoA ω-hydroxylase; CYP86A22 (gene name)

Systematic name: long-chain acyl-CoA,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (ω-hydroxylating)

Comments: A cytochrome P-450 (heme-thiolate) protein. The enzymes from solanaceous plants are involved in the biosynthesis of stigmatic estolide, a lipid-based polyester that forms a major component of the exudate.
