Comments [?]

case <OC:Methanosarcinaceae>
FUNCTIONPart of the ACDS complex that catalyzes the reversible cleavage of acetyl-CoA, allowing growth on acetate as sole source of carbon and energy. The alpha-epsilon subcomponent functions as a carbon monoxide dehydrogenase.
end case
case not <OC:Methanosarcinaceae>
FUNCTIONPart of the ACDS complex that catalyzes the reversible cleavage of acetyl-CoA, allowing autotrophic growth from CO(2). The alpha-epsilon subcomponent functions as a carbon monoxide dehydrogenase.
end case
CATALYTIC ACTIVITY Reaction=CO + 2 oxidized [2Fe-2S]-[ferredoxin] + H2O = 2 reduced [2Fe- 2S]-[ferredoxin] + CO2 + 2 H(+); Xref=Rhea:RHEA:21040, Rhea:RHEA- COMP:10000, Rhea:RHEA-COMP:10001, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:16526, ChEBI:CHEBI:17245, ChEBI:CHEBI:33737, ChEBI:CHEBI:33738; EC=1.2.7.4;
COFACTOR Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883; Note=Binds 7 [4Fe-4S] clusters per heterotetramer.;
COFACTOR Name=[Ni-4Fe-4S] cluster; Xref=ChEBI:CHEBI:47739; Note=Binds 2 [Ni-4Fe-4S] clusters per heterotetramer.;
case <OC:Methanosarcinaceae>
PATHWAYOne-carbon metabolism; methanogenesis from acetate.
end case
SUBUNITHeterotetramer of two alpha and two epsilon subunits. The ACDS complex is made up of alpha, epsilon, beta, gamma and delta subunits with a probable stoichiometry of (alpha(2)epsilon(2))(4)-beta(8)- (gamma(1)delta(1))(8).
DOMAINCluster B is an all-cysteinyl-liganded 4Fe-4S cluster; cluster C is a mixed Ni-Fe-S cluster which is the active site of CO oxidation. Cluster D is also an all-cysteinyl-liganded 4Fe-4S cluster that bridges the two subunits of the CODH dimer. Contains two additional 4Fe-4S clusters, dubbed E and F, that probably transport electrons from ferredoxin to the B cluster.
SIMILARITYBelongs to the Ni-containing carbon monoxide dehydrogenase family.
