(S)-6-hydroxynicotine oxidase

Class of enzymes

In enzymology, a (S)-6-hydroxynicotine oxidase (EC 1.5.3.5) is an enzyme that catalyzes the chemical reaction

(S)-6-hydroxynicotine + H2O + O2 1-(6-hydroxypyridin-3-yl)-4-(methylamino)butan-1-one + H2O2
Quick Facts Identifiers, EC no. ...

The 3 substrates of this enzyme are (S)-6-hydroxynicotine, H2O, and O2, whereas its two products are 1-(6-hydroxypyridin-3-yl)-4-(methylamino)butan-1-one and H2O2.

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with oxygen as acceptor. The systematic name of this enzyme class is (S)-6-hydroxynicotine:oxygen oxidoreductase. Other names in common use include L-6-hydroxynicotine oxidase, 6-hydroxy-L-nicotine oxidase, and 6-hydroxy-L-nicotine:oxygen oxidoreductase. It employs one cofactor, FAD.
