Protein

Sulfite reductase [NADPH] flavoprotein alpha-component

Gene

cysJ

Organism
Shewanella oneidensis (strain MR-1)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Component of the sulfite reductase complex that catalyzes the 6-electron reduction of sulfite to sulfide. This is one of several activities required for the biosynthesis of L-cysteine from sulfate. The flavoprotein component catalyzes the electron flow from NADPH -> FAD -> FMN to the hemoprotein component.UniRule annotation

Catalytic activityi

H2S + 3 NADP+ + 3 H2O = sulfite + 3 NADPH.UniRule annotation

Cofactori

Protein has several cofactor binding sites:
  • FADUniRule annotationNote: Binds 1 FAD per subunit.UniRule annotation
  • FMNUniRule annotationNote: Binds 1 FMN per subunit.UniRule annotation
