In enzymology a 2-oxobutyrate synthase (EC 1.2.7.2) is an enzyme that catalyzes the chemical reaction2-oxobutanoate + CoA + oxidized ferredoxin propanoyl-CoA + CO2 + reduced ferredoxinThe 3 substrates of this enzyme are 2-oxobutanoate CoA and oxidized ferredoxin whereas its 3 products are propanoyl-CoA CO2 and reduced ferredoxin.This enzyme belongs to the family of oxidoreductases specifically those acting on the aldehyde or oxo group of donor with an iron-sulfur protein as acceptor.
