CODH ...	Acetyl-CoA synthase/CO dehydrogenase (ACS/CODH) is a bifunctional enzyme that catalyses the reversible reduction of CO2 to CO (CODH activity, the beta subunit) and the synthesis or degradation of acetyl-CoA (catalysed by ACS, the alpha subunit). CODH contains the B-, C-, and D-clusters. This domain represents the middle and C-terminal regions of CODH which have an alpha/beta Rossmann-like fold and are the contribute ligands to the active site C-cluster. The C-cluster generates CO from CO2 and contains one Ni atom, four Fe atoms, and five labile sulfur atoms, arranged as an asymmetrical heteronuclear [Ni-4Fe-5S] cluster [1,2,6,7].	Domain
