Abstract

Model compounds of novel organic cofactor TTQ (tryptophan tryptophylquinone) of quinoprotein methylamine and aromatic amine dehydrogenases have been shown to interact with a series of metal ions in anhydrous organic media. Spectroscopic analyses including UV-vis, NMR, and resonance Raman indicate that the metal ion binds to the TTQ model compounds at their o-quinone moiety, the binding mode of which is similar to that ...
