Sulfite reductases (EC 1.8.99.1) are important enzymes in the process of sulfur metabolism.^[2] They catalyze the reduction of sulfite to hydrogen sulfide and water.^[2]^[3] Electrons for the reaction are provided by a dissociable molecule of either NADPH, bound flavins, or ferredoxins.^[4]

SO₃²⁻ (sulfite) + electron donor H₂S (hydrogen sulfide) + oxidized donor + 3 H₂O

Sulfite reductases belong to the family of oxidoreductases, and are found in archaea, bacteria, fungi, and plants.^[5] They are grouped as either assimilatory or dissimilatory sulfite reductases depending on their function, their spectroscopic properties, and their catalytic properties. This enzyme participates in selenoamino acid metabolism and sulfur assimilation. It employs two covalently coupled cofactors - an iron sulfur cluster and a siroheme - which deliver electrons to the substrate via this coupling.^[6]

The systematic name of this enzyme class is hydrogen-sulfide:acceptor oxidoreductase. Other names in common use include assimilatory sulfite reductase, assimilatory-type sulfite reductase, and hydrogen-sulfide:(acceptor) oxidoreductase.

The central step in the assimilation of sulfur is a six-electron reduction of sulfite to sulfide, catalyzed by the oxidoreductase NADPH-dependent assimilatory Sulfite Reductase (SiR). SiR is composed of two subunits. One is a multi-domain flavin-binding reductase (SiRFP) and the other an iron-contai
