Entry
EC 1.5.99.4                 Enzyme                                 
Name
nicotine dehydrogenase;
nicotine oxidase;
D-nicotine oxidase;
nicotine:(acceptor) 6-oxidoreductase (hydroxylating);
L-nicotine oxidase
Class
Oxidoreductases;
Acting on the CH-NH group of donors;
With other acceptors
BRITE hierarchy
Sysname
nicotine:acceptor 6-oxidoreductase (hydroxylating)
Reaction(IUBMB)
(S)-nicotine + acceptor + H2O = (S)-6-hydroxynicotine + reduced acceptor [RN:R02860]
Reaction(KEGG)
Substrate
(S)-nicotine [CPD:C00745];
acceptor [CPD:C00028];
H2O [CPD:C00001]
Product
(S)-6-hydroxynicotine [CPD:C01056];
reduced acceptor [CPD:C00030]
Comment
A metalloprotein (FMN). The enzyme can act on both the naturally found (S)-enantiomer and the synthetic (R)-enantiomer of nicotine, with retention of configuration in both cases [4].
