EC 1.14.19.67

Accepted name: salutaridine synthase

Reaction: (R)-reticuline + [reduced NADPH—hemoprotein reductase] + O2 = salutaridine + [oxidized NADPH—hemoprotein reductase] + 2 H2O

Other name(s): (R)-reticuline oxidase (C-C phenol-coupling)

Systematic name: (R)-reticuline,[reduced NADPH—hemoprotein reductase]:oxygen oxidoreductase (C-C phenol-coupling)

Comments: A cytochrome P-450 (heme-thiolate) protein found in plants. Forms the morphinan alkaloid salutaridine by intramolecular phenol oxidation of reticuline without the incorporation of oxygen into the product.
