Comments

CATALYTIC ACTIVITY: Pyruvate + CoA + 2 oxidized ferredoxin = acetyl-CoA + CO₂ + 2 reduced ferredoxin + 2 H⁺.
CATALYTIC ACTIVITY: 3-methyl-2-oxobutanoate + CoA + 2 oxidized ferredoxin = S-(2-methylpropanoyl)-CoA + CO₂ + 2 reduced ferredoxin + H⁺.
SUBUNIT: Heterotetramer of one alpha, one beta, one delta and one gamma chain.
