| Organism | Methanosarcina acetivorans [Complete proteome] [HAMAP] | ||||
| Taxonomic identifier | 2214 [NCBI] | ||||
| Taxonomic lineage | Archaea › Euryarchaeota › Methanomicrobia › Methanosarcinales › Methanosarcinaceae › Methanosarcina |
Protein attributes
| Sequence length | 805 AA. |
| Sequence status | Complete. |
| Sequence processing | The displayed sequence is not processed. |
| Protein existence | Inferred from homology. |
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. |
