>TIGR02066 dsrB sulfite reductase, dissimilatory-type beta subunit; InterPro: IPR011808 Dissimilatory sulphite reductase catalyzes the six-electron reduction of sulphite to sulphide, as the terminal reaction in dissimilatory sulphate reduction. It remains unclear however, whether trithionate and thiosulphate serve as intermediate compounds to sulphide, or as end products of sulphite reduction . Sulphite reductase is a multisubunit enzyme composed of dimers of either alpha/beta or alpha/beta/gamma subunits, each containing a siroheme and iron sulphur cluster prosthetic centre . Found in sulphate-reducing bacteria, these genes are commonly located in a unidirectional gene cluster . This entry describes the beta subunit of sulphite reductase.; GO: 0018551 hydrogensulfite reductase activity, 0051539 4 iron 4 sulfur cluster binding, 0006118 electron transport.
