Accepted name: pseudooxynicotine oxidase
Reaction: 4-(methylamino)-1-(pyridin-3-yl)butan-1-one + H2O + O2 = 4-oxo-4-(pyridin-3-yl)butanal + methylamine + H2O2
Glossary: 4-(methylamino)-1-(pyridin-3-yl)butan-1-one = pseudooxynicotine
4-oxo-4-(pyridin-3-yl)butanal = 3-succinoylsemialdehyde-pyridine
Systematic name: 4-(methylamino)-1-(pyridin-3-yl)butan-1-one:oxygen oxidoreductase (methylamine releasing)
Comments: Contains one non-covalently bound FAD molecule per dimer. This enzyme, characterized from the soil bacterium Pseudomonas sp. HZN6, is involved the nicotine degradation.
