A metallocofactor containing iron, sulfur, copper, and nickel has been, discovered in the enzyme carbon monoxide dehydrogenase/acetyl-CoA, (coenzyme A) synthase from Moorella thermoacetica (f. Clostridium, thermoaceticum). Our structure at 2.2 angstrom resolution reveals that the, cofactor responsible for the assembly of acetyl-CoA contains a [Fe4S4], cubane bridged to a copper-nickel binuclear site. The presence of these, three metals together in one cluster was unanticipated and suggests a, newly discovered role for copper in biology. The different active sites of, this bifunctional enzyme complex are connected via a channel, 138, angstroms long, that provides a conduit for carbon monoxide generated at, the C-cluster on one subunit to be incorporated into acetyl-CoA at the, A-cluster on the other subunit.

== Function ==
 +
[https://www.uniprot.org/uniprot/DCMB_MOOTH DCMB_MOOTH] 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.
