Comments

FUNCTION: The beta subunit (this protein) generates CO from CO(2), while the alpha subunit combines the CO with CoA and a methyl group to form acetyl-CoA. The methyl group, which is incorporated into acetyl-CoA, is transferred to the alpha subunit by a corrinoid iron-sulfur protein.
CATALYTIC ACTIVITY: CO + H₂O + 2 oxidized ferredoxin = CO₂ + 2 reduced ferredoxin + 2 H⁺.
CATALYTIC ACTIVITY: CO + H₂O + A = CO₂ + AH₂.
COFACTOR: Binds 1 nickel-iron-sulfur cluster per subunit.
COFACTOR: Binds 2 4Fe-4S clusters per homodimer.
SUBUNIT: Tetramer of two alpha and two beta chains.
