Glossary: 1-(6-hydroxypyridin-3-yl)-4-(methylamino)butan-1-one = 6-hydroxypseudooxynicotine
1-(2,6-dihydroxypyridin-3-yl)-4-(methylamino)butan-1-one = 2,6-dihydroxypseudooxynicotine
Systematic name: 1-(6-hydroxypyridin-3-yl)-4-(methylamino)butan-1-one:acceptor 6-oxidoreductase (hydroxylating)
Comments: Contains a cytidylyl molybdenum cofactor [3]. The enzyme, which participates in the nicotine degradation pathway, has been characterized from the soil bacterium Arthrobacter nicotinovorans [1,2].
