Taxonomic identifier

882 [NCBI]

Taxonomic lineage

Bacteria › Proteobacteria › Deltaproteobacteria › Desulfovibrionales › Desulfovibrionaceae › Desulfovibrio

Protein attributes

Sequence length	381 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

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. Binds 2 sirohemes per subunit.
Subunit structure	Heterohexamer of two alpha, two beta and two gamma subunits.
Sequence similarities	Contains 1 4Fe-4S ferredoxin-type domain.
