Protein Domain : Sulphite reductase [NADPH] flavoprotein, alpha chain IPR010199

Type  Family
Description  Escherichia coli NADPH-sulphite reductase (SiR) is a multimeric hemoflavoprotein composed of eight alpha-subunits (SiR-FP) and four beta-subunits (SiR-HP) that catalyses the six electron reduction of sulphite to sulphide. This is one of several activities required for the biosynthesis of L-cysteine from sulphate. The alpha component of NADPH-sulphite reductase is a flavoprotein, the beta component is a hemoprotein []. The flavoprotein component catalyses the electron flow from NADPH to FAD to FMN to the hemoprotein component.This entry describes an NADPH-dependent sulphite reductase flavoprotein subunit alpha. It binds one FAD and one FMN as prosthetic groups and contains an NADPH-binding domain [].
