Identification of an essential cysteine residue in human glutathione synthase.

Abstract

Glutathione is essential for a variety of cellular functions, and is synthesized from gamma-glutamylcysteine and glycine by the action of glutathione synthase (EC 6.3.2.3). Human glutathione synthase is a dimer of two identical subunits, each composed of 474 amino acids. Little is known about the structure-function relationships of mammalian glutathione… (More)
