2-oxobutyrate + CoA + oxidized methyl viologen
propanoyl-CoA + CO2 + reduced methyl viologen
the enzyme has a broad substrate specificity. In the presence of CoA, it oxidizes pyruvate, oxaloacetate, 2-oxobutyrate, and indol-3-pyruvate with specific activities of 7.4, 6.5, 3.6, and 0.3 U/mg, respectively. The enzyme reduces clostridial rubredoxin, clostridial and spinach ferredoxin, cytochrome c, FMN, and FAD. No activity is detected with NAD+, NADP+, and vitamin K1. The catalytic efficiencies or kcat/Km values for FAD and FMN are calculated to be 2400032000/min * M, which are about two orders of magnitude lower than observed for the likely physiological electron carriers of other pyruvate oxidoreductases. Therefore, it is unlikely that flavins are the physiological electron carrier of the methanococcal pyruvate oxidoreductase

pyruvate ferredoxin oxidoreductase functions as a CoA-dependent pyruvate decarboxylase. Ferredoxin is not necessary for the pyruvate decarboxylase activity of POR. At 80°C (pH 8.0), the apparent Vm value for pyruvate decarboxylation is about 40% of the apparent Vm value for pyruvate oxidation rate (using Pyrococcus furiosus ferredoxin as the electron acceptor)

-
the ability of the 4Fe-ferredoxin to accept electrons is not absolutely dependent upon Asp14 (of ferredoxin), as this residue can be effectively replaced by Cys. However, the efficiency of electron transfer is compromised if Asp14 is replaced by Ser, or if the 4Fe-cluster is converted to the 3Fe-form, but Asp14 does not appear to offer any kinetic advantage over the expected Cys

the addition of pyruvate to oxidized POR produces an isotropic signal centered at g = 2.01, assigned to a (hydroxyethy1)thiamine pyrophosphate radical intermediate. Incubation of the oxidized enzyme with CoA results in the partial reduction of the copper site in POR. The addition of both pyruvate and CoA to the POR in its oxidized state results in the reduction of the same iron-sulfur center that is reduced by sodium dithionite
