In enzymology a 3-methyl-2-oxobutanoate dehydrogenase (ferredoxin) (EC 1.2.7.7) is an enzyme that catalyzes the chemical reaction3-methyl-2-oxobutanoate + CoA + oxidized ferredoxin S-(2-methylpropanoyl)-CoA + CO2 + reduced ferredoxinThe 3 substrates of this enzyme are 3-methyl-2-oxobutanoate CoA and oxidized ferredoxin whereas its 3 products are S-(2-methylpropanoyl)-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.
