catalytic activity:ATP + gamma-L-glutamyl-L-cysteine + glycine = ADP + phosphate + glutathione.,disease:Defects in GSS are the cause of glutathione synthetase deficiency (GSS deficiency) [MIM:266130]; referred to as 5-oxoprolinuria. It is a severe form characterized by an increased rate of hemolysis and defective function of the central nervous system.,disease:Defects in GSS are the cause of glutathione synthetase deficiency of erythrocytes [MIM:231900]. It is a mild form causing hemolytic anemia.,pathway:Sulfur metabolism; glutathione biosynthesis; glutathione from L-cysteine and L-glutamate: step 2/2.,similarity:Belongs to the eukaryotic GSH synthase family.,subunit:Homodimer.,
