Well-established quality management system.
Reaction
(S)-6-hydroxynicotine + H2O + O2 = 1-(6-hydroxypyridin-3-yl)-4-(methylamino)butan-1-one + H2O2 (overall reaction)
(1a) (S)-6-hydroxynicotine + O2 = 5-(N-methyl-4,5-dihydro-1H-pyrrol-2-yl)pyridin-2-ol + H2O2
(1b) 5-(N-methyl-4,5-dihydro-1H-pyrrol-2-yl)pyridin-2-ol + H2O = 1-(6-hydroxypyridin-3-yl)-4-(methylamino)butan-1-one (spontaneous)
Systematic Name
(S)-6-hydroxynicotine:oxygen oxidoreductase
Function
A flavoprotein (FAD). The enzyme, which participates in nicotine degradation, is specific for the (S) isomer of 6-hydroxynicotine. The bacterium Arthrobacter nicotinovorans, in which this enzyme was originally discovered, has a different enzyme that catalyses a similar reaction with the less common (R)-isomer (cf. EC 1.5.3.6, (R)-6-hydroxynicotine oxidase).
Other name
L-6-hydroxynicotine oxidase; 6-hydroxy-L-nicotine oxidase; 6-hydroxy-L-nicotine:oxygen oxidoreductase; nctB (gene name)
