(1) An S-((1E)-1-(hydroxyimino)-omega-(methylsulfanyl)alkyl)-L- glutathione + H(2)O = an S-((1E)-1-(hydroxyimino)-omega- (methylsulfanyl)alkyl)-L-cysteinylglycine + L-glutamate. (2) (E)-1-(glutathion-S-yl)-2-(1H-indol-3-yl)acetohydroximate + H(2)O = (E)-1-(glycylcystein-S-yl)-2-(1H-indol-3-yl)acetohydroximate + L-glutamate. (3) 2-(glutathion-S-yl)-2-(1H-indol-3-yl)acetonitrile + H(2)O = 2-(glycylcystein-S-yl)-2-(1H-indol-3-yl)acetonitrile + L-glutamate. (4) (Z)-1-(glutathion-S-yl)-2-phenylacetohydroximate + H(2)O = (Z)-1- (glycylcystein-S-yl)-2-phenylacetohydroximate + L-glutamate. |
