Comments
  • FUNCTION: Catalyzes the reduction of sulfite to sulfide. This is the terminal oxidation reaction in sulfate respiration.
  • CATALYTIC ACTIVITY: (O3S.S.SO3)2- + acceptor + 2 H2O + OH- = 3 HSO3- + reduced acceptor.
  • COFACTOR: Binds 1 4Fe-4S cluster per subunit.
  • COFACTOR: Binds 2 sirohemes per subunit.
