Protein attributes
| Sequence length | 198 AA. |
| Sequence status | Fragment. |
| Protein existence | Inferred from homology |
General annotation (Comments)
| Function | Catalyzes the reduction of sulfite to sulfide. This is the terminal oxidation reaction in sulfate respiration, a process catalyzed by the sulfate-reducing bacteria. |
| Catalytic activity | (O3S.S.SO3)2- + acceptor + 2 H2O + OH- = 3 HSO3- + reduced acceptor. |
| Cofactor | Binds 1 4Fe-4S cluster per subunit By similarity. Binds 2 sirohemes per subunit By similarity. |
| Subunit structure | Heterohexamer of two alpha, two beta and two gamma subunits. |
| Sequence similarities | Contains 1 4Fe-4S ferredoxin-type domain. |
