Nicotine dehydrogenase

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with other acceptors. The systematic name of this enzyme class is nicotine:acceptor 6-oxidoreductase (hydroxylating). Other names in common use include nicotine oxidase, D-nicotine oxidase, nicotine:(acceptor) 6-oxidoreductase (hydroxylating), and L-nicotine oxidase. It has 2 cofactors: metal, and FMN.
