| case <OC:Methanosarcinaceae> | |
| FUNCTION | Part of a complex that catalyzes the reversible cleavage of acetyl-CoA, allowing growth on acetate as sole source of carbon and energy. The alpha-epsilon complex generates CO from CO(2), while the beta subunit (this protein) 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 beta subunit by a corrinoid iron- sulfur protein (the gamma-delta complex). |

| case not <OC:Methanosarcinaceae> | |
| FUNCTION | Part of a complex that catalyzes the reversible cleavage of acetyl-CoA, allowing autotrophic growth from CO(2). The alpha-epsilon complex generates CO from CO(2), while the beta subunit (this protein) 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 beta subunit by a corrinoid iron-sulfur protein (the gamma-delta complex). |
| end case | |
| CATALYTIC ACTIVITY | Reaction=acetyl-CoA + Co(I)-[corrinoid Fe-S protein] + H(+) = CO + CoA + methyl-Co(III)-[corrinoid Fe-S protein]; Xref=Rhea:RHEA:45212, Rhea:RHEA-COMP:11110, Rhea:RHEA-COMP:11111, ChEBI:CHEBI:15378, ChEBI:CHEBI:17245, ChEBI:CHEBI:57287, ChEBI:CHEBI:57288, ChEBI:CHEBI:85033, ChEBI:CHEBI:85035; EC=2.3.1.169; |
| COFACTOR | Name=[Ni-Fe-S] cluster; Xref=ChEBI:CHEBI:60400; Note=Binds 1 [Ni-Fe-S] cluster.; |
| case <OC:Methanosarcinaceae> | |
| PATHWAY | One-carbon metabolism; methanogenesis from acetate. |
| end case | |
| SUBUNIT | Monomer. The ACDS complex is made up of alpha, epsilon, beta, gamma and delta chains with a probable stoichiometry of (alpha(2)epsilon(2))(4)-beta(8)-(gamma(1)delta(1))(8). |
| SIMILARITY | Belongs to the CdhC family. |
