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.
