Catalyzes the formation of the morphinan alkaloid salutaridine by intramolecular phenol oxidation of (R)-reticuline without the incorporation of oxygen into the product (PubMed:19567876, PubMed:22098111). Can also use (R)-norreticuline as substrate (PubMed:19567876). (R)-reticuline + O2 + reduced [NADPH--hemoprotein reductase] = H(+) + 2 H2O + oxidized [NADPH--hemoprotein reductase] + salutaridine kcat is 1.64 min(-1) for (R)-reticuline. Optimum pH is 8.5. Optimum temperature is 30 degrees Celsius. Up-regulated by elicitor treatment. Belongs to the cytochrome P450 family.
