Mechanism of the Clostridium thermoaceticum Pyruvate:Ferredoxin Oxidoreductase:  Evidence for the Common Catalytic Intermediacy of the Hydroxyethylthiamine Pyropyrosphate Radical

DOI: 10.1021/bi970403k Authors: Saurabh Menon, Stephen W. Ragsdale Abstract: The cofactor content and mechanism of pyruvate:ferredoxin oxidoreductase (PFOR) are controversial. By using rapid freeze-quench EPR and stopped-flow spectroscopy, the elementary steps that...
