CC -!- FUNCTION: Part of the ACDS complex that catalyzes the reversible
CC cleavage of acetyl-CoA, allowing growth on acetate as sole source of
CC carbon and energy. The alpha-epsilon subcomponent functions as a carbon
CC monoxide dehydrogenase. {ECO:0000255|HAMAP-Rule:MF_01137}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=CO + H2O + 2 oxidized [2Fe-2S]-[ferredoxin] = CO2 + 2 H(+) + 2
CC reduced [2Fe-2S]-[ferredoxin]; Xref=Rhea:RHEA:21040, Rhea:RHEA-

CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01137};
CC Note=Binds 7 [4Fe-4S] clusters per heterotetramer. {ECO:0000255|HAMAP-
CC Rule:MF_01137};
CC -!- COFACTOR:
CC Name=[Ni-4Fe-4S] cluster; Xref=ChEBI:CHEBI:47739;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01137};
CC Note=Binds 2 [Ni-4Fe-4S] clusters per heterotetramer.
CC {ECO:0000255|HAMAP-Rule:MF_01137};
CC -!- PATHWAY: One-carbon metabolism; methanogenesis from acetate.
CC {ECO:0000255|HAMAP-Rule:MF_01137}.
CC -!- SUBUNIT: Heterotetramer of two alpha and two epsilon subunits. The ACDS
CC complex is made up of alpha, epsilon, beta, gamma and delta subunits
CC with a probable stoichiometry of (alpha(2)epsilon(2))(4)-beta(8)-
CC (gamma(1)delta(1))(8). {ECO:0000255|HAMAP-Rule:MF_01137}.
CC -!- DOMAIN: Cluster B is an all-cysteinyl-liganded 4Fe-4S cluster; cluster
CC C is a mixed Ni-Fe-S cluster which is the active site of CO oxidation.
CC Cluster D is also an all-cysteinyl-liganded 4Fe-4S cluster that bridges
CC the two subunits of the CODH dimer. Contains two additional 4Fe-4S
CC clusters, dubbed E and F, that probably transport electrons from
CC ferredoxin to the B cluster. {ECO:0000255|HAMAP-Rule:MF_01137}.
CC -!- SIMILARITY: Belongs to the Ni-containing carbon monoxide dehydrogenase
CC family. {ECO:0000255|HAMAP-Rule:MF_01137}.
