FUNCTIONSynthesizes glutathione from L-glutamate and L-cysteine via gamma-L-glutamyl-L-cysteine.
CATALYTIC ACTIVITY Reaction=ATP + L-cysteine + L-glutamate = ADP + gamma-L-glutamyl-L- cysteine + H(+) + phosphate; Xref=Rhea:RHEA:13285, ChEBI:CHEBI:15378, ChEBI:CHEBI:29985, ChEBI:CHEBI:30616, ChEBI:CHEBI:35235, ChEBI:CHEBI:43474, ChEBI:CHEBI:58173, ChEBI:CHEBI:456216; EC=6.3.2.2;
CATALYTIC ACTIVITY Reaction=ATP + gamma-L-glutamyl-L-cysteine + glycine = ADP + glutathione + H(+) + phosphate; Xref=Rhea:RHEA:13557, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:57305, ChEBI:CHEBI:57925, ChEBI:CHEBI:58173, ChEBI:CHEBI:456216; EC=6.3.2.3;
