Protein
Glutathione reductase, cytosolic
Gene
N/A
Organism
Pisum sativum (Garden pea)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

Maintains high levels of reduced glutathione in the cytosol. May play a role in the restoration of the post-stress redox state of the cytosolic glutathione pool.

Catalytic activityi

2 glutathione + NADP+ = glutathione disulfide + NADPH.

Cofactori

Binds 1 FAD per subunit By similarity.
