In enzymology, a morphine 6-dehydrogenase (EC 1.1.1.218) is an enzyme that catalyzes the chemical reaction
- morphine + NAD(P)+ [math]\displaystyle{ \rightleftharpoons }[/math] morphinone + NAD(P)H + H+
The 3 substrates of this enzyme are morphine, NAD+, and NADP+, whereas its 4 products are morphinone, NADH, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is morphine:NAD(P)+ 6-oxidoreductase. Other names in common use include naloxone reductase, and reductase, naloxone. This enzyme participates in alkaloid biosynthesis i. This enzyme has at least one effector, Mercaptoethanol.
