Names and origin

Protein names	Recommended name: Carbon monoxide dehydrogenase/acetyl-CoA synthase subunit beta Short name=CODH/ACS Short name=Carbon monoxide dehydrogenase subunit Short name=CODH subunit EC=1.2.7.4 EC=1.2.99.2
Organism	Moorella thermoacetica (Clostridium thermoaceticum)
Taxonomic identifier	1525 [NCBI]
Taxonomic lineage	Bacteria › Firmicutes › Clostridia › Thermoanaerobacterales › Thermoanaerobacteriaceae › Moorella group › Moorella

Protein attributes

Sequence length	674 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	The beta subunit (this protein) generates CO from CO₂, 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⁺. CO + H₂O + A = CO₂ + AH₂.
Cofactor	Binds 1 nickel-iron-sulfur cluster per subunit. Binds 2 4Fe-4S clusters per homodimer.
Subunit structure	Tetramer of two alpha and two beta chains.
