Pyruvate-ferredoxin oxidoreductase (PFOR) is an enzyme of the fermentation cycle which catalyzes the oxidative decarboxylation of pyruvate to acetyl CoA and CO2. This reaction provides the electron source for the reduction of ferredoxin. The reaction is CoA-dependent and contains thiamine diphosphate (TDP). PFOR contains iron-sulfur clusters (Fe4S4).
