[1]	NUCLEOTIDE SEQUENCE [GENOMIC DNA]. STRAIN=ATCC 19364 / DSM 1382 / NCIB 9332 / VKM B-1759; Hipp W.M., Trueper H.G.; Submitted (DEC-1996) to the EMBL/GenBank/DDBJ databases.

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).
COFACTOR: Binds 2 sirohemes per subunit (By similarity).
SUBUNIT: Heterohexamer of two alpha, two beta and two gamma subunits (By similarity).
