Aminotransferase, l-amino acid oxidase and β-lyase reactions involving l-cysteine S-conjugates found in allium extracts

An interesting side finding of the present work is that rat liver mitochondria are more active than rat liver cytosol in catalyzing a cysteine S-conjugate β-lyase reaction with the mitochondrial protoxicant S-(1,1,2,2-tetrafluoroethyl)-l-cysteine (TFEC) at physiological pH and at low substrate concentration.
