(S)-6-hydroxynicotine oxidase

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


 * (S)-6-hydroxynicotine + H$2$O + O$2$ $$\rightleftharpoons$$ 1-(6-hydroxypyridin-3-yl)-4-(methylamino)butan-1-one + H$2$O$2$

The 3 substrates of this enzyme are (S)-6-hydroxynicotine, H$2$O, and O$2$, whereas its two products are 1-(6-hydroxypyridin-3-yl)-4-(methylamino)butan-1-one and H$2$O$2$.

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.
