Reaction: dodecanoate + [reduced NADPH—hemoprotein reductase] + O2 = 7-hydroxydodecanoate + [oxidized NADPH—hemoprotein reductase] + H2O
Glossary: laurate = dodecanoate
Other name(s): CYP703A2 (gene name)
Systematic name: dodecanoate,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (7-hydroxylating)
Comments: A cytochrome P-450 (heme-thiolate) protein found in plants. The enzyme is involved in the synthesis of sporopollenin - a complex polymer found at the outer layer of spores and pollen. It can also act on decanoate (C10), myristate (C14), and palmitate (C16) with lower activity. The enzyme also produces a small amount of products that are hydroxylated at neighboring positions (C-6, C-8 and C-9).
