FUNCTIONCatalyzes the synthesis of gamma-glutamylcysteine (gamma-GC). This compound is used as substrate for the biosynthesis of the low- molecular thiol compound ergothioneine.
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;
PATHWAYAmino-acid biosynthesis; ergothioneine biosynthesis.
SIMILARITYBelongs to the glutamate--cysteine ligase type 2 family. EgtA subfamily.
