General annotation (Comments)

Function	Part of a complex that catalyzes the reversible cleavage of acetyl-CoA, allowing growth on acetate as sole source of carbon and energy By similarity.
Catalytic activity	CO + H₂O + A = CO₂ + AH₂. HAMAP MF_01137
Cofactor	Binds 7 4Fe-4S clusters per heterotetramer Potential. Binds 2 nickel-iron-sulfur clusters per heterotetramer Potential.
Pathway	One-carbon metabolism; methanogenesis from acetate. HAMAP MF_01137
Subunit structure	Heterotetramer of two alpha and two epsilon chains. The ACDS complex is made up of alpha, epsilon, beta, gamma and delta chains with a probable stoichiometry of (alpha₂epsilon₂)(4)-beta(8)-(gamma₁delta₁)₈ Potential.
Domain	Cluster B is an all-cysteinyl-liganded 4Fe4S cluster; cluster C is a mixed Ni-Fe-S cluster which appears to be the active site of CO oxidation. Cluster D is also an all-cysteinyl-liganded 4Fe4S cluster that bridges the two subunits of the CODH dimer. May contain two additional 4Fe-4S clusters, dubbed E and F, that might reroute electron transfer along different paths. HAMAP MF_01137
Sequence similarities	Belongs to the Ni-containing carbon monoxide dehydrogenase family. Contains 2 4Fe-4S ferredoxin-type domains.
