CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-cysteine + L-glutamate = ADP + gamma-L-glutamyl-L-
CC cysteine + H(+) + phosphate; Xref=Rhea:RHEA:13285, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:29985, ChEBI:CHEBI:30616, ChEBI:CHEBI:35235,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58173, ChEBI:CHEBI:456216; EC=6.3.2.2;
CC -!- PATHWAY: Sulfur metabolism; glutathione biosynthesis; glutathione from
CC L-cysteine and L-glutamate: step 1/2.
CC -!- SUBUNIT: Homodimer or monomer when oxidized or reduced, respectively.
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000250}.
CC -!- PTM: The Cys-156-Cys-376 disulfide bridge is known to modulate the
CC enzyme activity according to the redox status. The oxidized form
CC constitutes the active enzyme (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the carboxylate-amine ligase family. Glutamate--
CC cysteine ligase type 2 subfamily. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAD48598.1; Type=Erroneous initiation; Evidence={ECO:0000305};
