DE   glucosinolate gamma-glutamyl hydrolase.
CA   (1) an S-[(1E)-1-(hydroxyimino)-omega-(methylsulfanyl)alkyl]-L-
CA   glutathione + H2O = an S-[(1E)-1-(hydroxyimino)-omega-
CA   (methylsulfanyl)alkyl]-L-cysteinylglycine + L-glutamate.
CA   (2) (E)-1-(glutathione-S-yl)-2-(1H-indol-3-yl)acetohydroximate + H2O =
CA   (E)-1-(glycyl-L-cystein-S-yl)-2-(1H-indol-3-yl)acetohydroximate +
CA   L-glutamate.
CA   (3) 2-(glutathion-S-yl)-2-(1H-indol-3-yl)acetonitrile + H2O = 2-(glycyl-
CA   L-cystein-S-yl)-2-(1H-indol-3-yl)acetonitrile + L-glutamate.
CA   (4) (Z)-1-(glutathione-S-yl)-2-phenylacetohydroximate + H2O = (Z)-1-
CA   (glycyl-L-cystein-S-yl)-2-phenylacetohydroximate + L-glutamate.
CC   -!- This enzyme, characterized from the plant Arabidopsis thaliana,
CC       participates in the biosynthesis of the plant defense compounds
CC       glucosinolates and camalexin.
CC   -!- It is the only known plant enzyme capable of hydrolyzing the gamma-
CC       glutamyl residue of glutathione in the cytosol.
