  • Title: Evidence for methoxatin (pyrroloquinolinequinone) as the cofactor in bovine plasma amine oxidase from resonance Raman spectroscopy.
    Author: Moog RS, McGuirl MA, Cote CE, Dooley DM.
    Journal: Proc Natl Acad Sci U S A; 1986 Nov; 83(22):8435-9. PubMed ID: 3464962.
    Abstract:
    Resonance Raman spectra of the 2,4-dinitrophenylhydrazine derivatives of bovine plasma amine oxidase [amine:oxygen oxidoreductase (deaminating) (copper-containing), EC 1.4.3.6] have been measured. Detailed comparisons to the spectra of the corresponding derivatives of methoxatin (pyrroloquinolinequinone), pyridoxal, and other aldehydes and diones provide further evidence that covalently bound methoxatin or a closely similar derivative is the organic cofactor in copper-containing amine oxidases.
