Enzyme Information
| 1.2.7.1 |
Pyruvate synthase.
based on mapping to UniProt P94692
Pyruvate + CoA + 2 oxidized ferredoxin = acetyl-CoA + CO(2) + 2 reduced ferredoxin + 2 H(+).
-!- The enzyme also decarboxylates 2-oxobutanoate with lower efficiency, but shows no activity with 2-oxoglutarate. -!- This enzyme is a member of the 2-oxoacid oxidoreductases, a family of enzymes that oxidatively decarboxylate different 2-oxoacids to form their CoA derivatives, and are differentiated based on their substrate specificity. -!- For examples of other members of this family, see EC 1.2.7.3 and EC 1.2.7.7.
