FUNCTION: Synthesizes glutathione from L-glutamate and L-cysteine via gamma-L-glutamyl-L-cysteine (By similarity).
CATALYTIC ACTIVITY: ATP + L-glutamate + L-cysteine = ADP + phosphate + gamma-L-glutamyl-L-cysteine.
CATALYTIC ACTIVITY: ATP + gamma-L-glutamyl-L-cysteine + glycine = ADP + phosphate + glutathione.
PATHWAY: Sulfur metabolism; glutathione biosynthesis; glutathione from L-cysteine and L-glutamate: step 1/2.
PATHWAY: Sulfur metabolism; glutathione biosynthesis; glutathione from L-cysteine and L-glutamate: step 2/2.
SUBUNIT: Monomer (By similarity).
SIMILARITY: In the N-terminal section; belongs to the glutamate--cysteine ligase type 1 family. Type 2 subfamily.
