DE   3-methyl-2-oxobutanoate dehydrogenase (ferredoxin).
AN   2-ketoisovalerate ferredoxin reductase.
AN   2-oxoisovalerate ferredoxin reductase.
AN   3-methyl-2-oxobutanoate synthase (ferredoxin).
AN   Branched-chain ketoacid ferredoxin reductase.
AN   Branched-chain oxo acid ferredoxin reductase.
AN   Keto-valine-ferredoxin oxidoreductase.
AN   Ketoisovalerate ferredoxin reductase.

AN   VOR.
CA   3-methyl-2-oxobutanoate + CoA + 2 oxidized ferredoxin =
CA   S-(2-methylpropanoyl)-CoA + CO(2) + 2 reduced ferredoxin + H(+).
CF   CoA; Iron-sulfur; Tungsten-molybdopterin.
CC   -!- One of four 2-oxoacid oxidoreductases that are differentiated by
CC       their abilities to oxidatively decarboxylate different 2-oxoacids and
CC       form their CoA derivatives (see also EC 1.2.7.1, EC 1.2.7.3 and
CC       EC 1.2.7.8).
CC   -!- Preferentially utilizes 2-oxo-acid derivatives of branched chain
CC       amino acids, e.g. 3-methyl-2-oxopentanoate, 4-methyl-2-oxo-
CC       pentanoate, 2-oxobutyrate and 3-methylthiopropanamine.
