CC -!- FUNCTION: Catalyzes the hydrolysis of the amide bond in N-(4-
CC oxoglutarate)-L-cysteinylglycine (deaminated glutathione), a metabolite
CC repair reaction to dispose of the harmful deaminated glutathione
CC (PubMed:30692244). Possesses amidase activity toward deaminated
CC ophthalmate in vitro (PubMed:30692244). {ECO:0000269|PubMed:30692244}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=H2O + N-(4-oxoglutaryl)-L-cysteinylglycine = 2-oxoglutarate +
CC L-cysteinylglycine; Xref=Rhea:RHEA:54532, ChEBI:CHEBI:15377,

CC Kinetic parameters:
CC KM=35 uM for N-(4-oxoglutarate)-L-cysteinylglycine
CC {ECO:0000269|PubMed:30692244};
CC KM=6.7 uM for ophthalmate {ECO:0000269|PubMed:30692244};
CC Vmax=7.9 umol/min/mg enzyme with N-(4-oxoglutarate)-L-
CC cysteinylglycine as substrate {ECO:0000269|PubMed:30692244};

CC {ECO:0000303|PubMed:30692244};
CC IsoId=Q94JV5-2; Sequence=VSP_060389;
CC -!- DISRUPTION PHENOTYPE: No visible phenotype under normal growth
CC conditions, but the accumuluation of N-(4-oxoglutarate)-L-
CC cysteinylglycine (deaminated glutathione) in mutant plants is up to 70-
CC fold higher than in the wild type. {ECO:0000269|PubMed:30692244}.
CC -!- SIMILARITY: Belongs to the nitrilase superfamily. NIT1/NIT2 family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=CAB78004.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
