The Multistep, Eight-Electron Oxidation Catalyzed by the Cofactorless Oxidase, PqqC: Identification of Chemical Intermediates and their Dependence on Molecular Oxygen

The final step of the biosynthesis of the prokaryotic cofactor, PQQ, is catalyzed by PqqC, a cofactorless oxidase that brings about a ring closure and overall eight-electron oxidation of its substrate. Time-dependent acid quenching and subsequent HPLC separation and mass spectrometric analyses of re...
