gamma-glutamylcysteine synthetase

(redirected from g-glutamylcysteine synthetase)

γ-glu·ta·myl·cys·teine syn·the·tase

an enzyme that catalyzes the first step in glutathione biosynthesis, reacting l-glutamate, l-cysteine, and ATP to form γ-glutamylcysteine, ADP, and orthophosphate; inhibited by thiols such as glutathione and cysteamine.

While, g-glutamylcysteine synthetase (g-GCS) is a rate-limiting enzyme in de novo synthesis of GSH and it plays a pivotal role in GSH homeostasis (Hibi et al., 2004).
Two enzymes are used in the synthesis of glutathione: g-glutamylcysteine synthetase (g-Glu-CysSyn), and glutathione synthetase (GS).
