GCL is specific for the glutamyl moiety and is regulated physiologically by: (a) non-allosteric feedback competitive inhibition by GSH (Ki=2.3mM), which involves binding of GSH to the glutamate and another site on the enzyme [8, 9] and (b) availability of its precursor, cysteine [1] .The apparent Km values of GCL for glutamate is 1.8 mM, and for cysteine and 0.10.3 mM [9]
