In Pseudomonas putida, the flavoprotein nicotine oxidoreductase (NicA2) catalyzes the oxidation of (S)-nicotine to N-methyl-myosmine, which is nonenzymatically hydrolyzed to pseudooxynicotine. Structural analysis reveals a monoamine oxidase (MAO)-like fold with a conserved FAD-binding domain and variable substrate-binding domain. The flavoenzyme has a unique variation of the classic aromatic cage with flanking residue pair W427/N462. Previous mechanistic studies using O2 as the oxidizing substrate show that NicA2 has a low apparent K
