>TIGR02064 dsrA sulfite reductase, dissimilatory-type alpha subunit; InterPro: IPR011806 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 .; GO: 0018551 hydrogensulfite reductase activity, 0020037 heme binding, 0051539 4 iron 4 sulfur cluster binding.
