ID 1.2.7.1 DE pyruvate synthase. AN 2-oxobutyrate-ferredoxin oxidoreductase. AN 2-oxobutyrate synthase. AN alpha-ketobutyrate-ferredoxin oxidoreductase. AN alpha-ketobutyrate synthase. AN pyruvate oxidoreductase. AN pyruvate synthetase. AN pyruvic-ferredoxin oxidoreductase. CA CoA + 2 oxidized [2Fe-2S]-[ferredoxin] + pyruvate = acetyl-CoA + CO2 + CA H(+) + 2 reduced [2Fe-2S]-[ferredoxin]. CC -!- The enzyme also decarboxylates 2-oxobutanoate with lower efficiency, CC but shows no activity with 2-oxoglutarate. CC -!- This enzyme is a member of the 2-oxoacid oxidoreductases, a family of CC enzymes that oxidatively decarboxylate different 2-oxoacids to form CC their CoA derivatives, and are differentiated based on their CC substrate specificity. CC -!- For examples of other members of this family, see EC 1.2.7.3 and CC EC 1.2.7.7.
