Protein

Sulfite reductase [NADPH] hemoprotein beta-component

Gene

cysI

Organism
Vibrio splendidus (strain LGP32) (Vibrio splendidus (strain Mel32))
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.UniRule annotation

Catalytic activityi

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

Cofactori

Binds 1 siroheme per subunit.UniRule annotation
Binds 1 4Fe-4S cluster per subunit.UniRule annotation
