Glutathione reductase, also known as GSH reductase, converts oxidized glutathione (glutathione disulfide) to two molecules of reduced gluthatione (GSH).

Structure

Glutathione reductase belongs to the larger family of flavoezymes, which use a flavin adenine dinucleotide (FAD) or flavin mononucleotide (FMN) in catalysis. It is an oxiodrecutase homodimer of 52kD monomers of which, each has three domains: 1. NADPH-binding domain, 2. FAD-binding domain, 3. dimerization domain.

Reaction

The action of glutathione reductase proceeds through a cyclic series of structures in differing redox states (Figure 1). Initiating the reduction, NADPH binds to glutathione reductase to transiently reduce the flavin co-factor. By forming a transient covalent
