KEGG   ENZYME: 1.14.19.67
Entry
EC 1.14.19.67               Enzyme                                 
Name
salutaridine synthase;
(R)-reticuline oxidase (C-C phenol-coupling)
Class
Oxidoreductases;
Acting on paired donors, with incorporation or reduction of molecular oxygen;
With oxidation of a pair of donors resulting in the reduction of O2 to two molecules of water
Sysname
(R)-reticuline,[reduced NADPH---hemoprotein reductase]:oxygen oxidoreductase (C-C phenol-coupling)
Reaction(IUBMB)
(R)-reticuline + [reduced NADPH---hemoprotein reductase] + O2 = salutaridine + [oxidized NADPH---hemoprotein reductase] + 2 H2O [RN:R04696]
Reaction(KEGG)
R04696
Substrate
(R)-reticuline [CPD:C05178];
[reduced NADPH---hemoprotein reductase] [CPD:C03024];
O2 [CPD:C00007]
Product
salutaridine [CPD:C05179];
[oxidized NADPH---hemoprotein reductase] [CPD:C03161];
H2O [CPD:C00001]
Comment
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.
