Subunit of: glutathione ABC transporter

Subunit composition of glutathione ABC transporter = [GsiA]2[GsiB][GsiD][GsiC]
         glutathione ABC transporter - ATP binding subunit = GsiA (summary available)
         glutathione ABC transporter - periplasmic binding protein = GsiB (summary available)
         glutathione ABC transporter - membrane subunit = GsiD (summary available)
         glutathione ABC transporter - membrane subunit = GsiC (summary available)

The GsiABCD glutathione transporter is a member of the ATP Binding Cassette (ABC) superfamily of transporters. Based on sequence similarity, GsiA is predicted to be the ATP-binding component, GsiB is predicted to be the periplasmic binding component, and GsiC and GsiD are predicted to be inner membrane components. Mutation of any component impairs the ability of E. coli to transport the glutathione molecule into the cell. Expression of the cloned genes in their respective mutants restores their ability to transport glutathione. Transport by the glutathione ABC transporter is one of two known mechanisms for salvage of glutathione excreted from the cell. The other involves hydrolysis of glutathione by γ-glutamyl transpeptidase in the periplasm to yield glutamic acid and cysteinylglycine which can be taken back into the cell [Suzuki05].
