1.5.3.5 | (S)-6-hydroxynicotine + H2O + O2 |
the enzyme catalyzes the oxidation of (S)-6-hydroxynicotine to 6-hydroxypseudooxynicotine during microbial catabolism of nicotine |

? |
1.5.3.5 | (S)-6-hydroxynicotine + H2O + O2 |
the enzyme converts (S)-6-hydroxynicotine into 6-hydroxy-N-methylmyosmine which then spontaneously hydrolyzes into 6-hydroxypseudooxynicotine. (S)-6-Hydroxynicotine is the preferred substrate in vivo. The enzyme shows no activities toward the R enantiomer of nicotine or 6-hydroxynicotine |

1.5.3.5 | (S)-nicotine + H2O + O2 |
the enzyme converts (S)-nicotine into N-methylmyosmine, which spontaneously hydrolyzes into pseudooxynicotine |
Shinella sp. |
N-methylmyosmine + H2O2 |
- |
? |
1.5.3.5 | (S)-nicotine + H2O + O2 |
N-methyl-myosmine, which is nonenzymatically hydrolyzed to pseudooxynicotine. The flavoenzyme preferentially oxidizes tertiary amines with an efficient reductive half-reaction and a very slow oxidative half-reaction when O2 is the oxidizing substrate, suggesting that the true oxidizing agent is unknown |
