| Description | Sulphite reductases (SiRs) and related nitrite reductases (NiRs) catalyse the six-electron reduction reactions of sulphite to sulphide, and nitrite to ammonia, respectively. The Escherichia coli SiR enzyme is a complex composed of two proteins, a flavoprotein alpha-component (SiR-FP) and a hemoprotein beta-component (SiR-HP), and has an alpha(8)beta(4) quaternary structure [ ]. SiR-FP contains both FAD and FMN, while SiR-HP contains a Fe(4)S(4) cluster coupled to a sirohaem through a cysteine bridge. Electrons are transferred from NADPH to FAD, and on to FMN in SiR-FP, from which they are transferred to the metal centre of SiR-HP, where they reduce the siroheme-bound sulphite. |
