| Other name(s): |
nicotine oxidase; D-nicotine oxidase; nicotine:(acceptor) 6-oxidoreductase (hydroxylating); L-nicotine oxidase; nicotine dehydrogenase (incorrect) |
| Systematic name: |
nicotine:acceptor 6-oxidoreductase (hydroxylating) |
| Comments: |
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]. |
