it is concluded that mercapturic acids are deacetylated to the corresponding cysteine conjugates by cytosolic ( n-ac-pcbc , n-ac-tcvc and n-ac-dcvc ) and bacterial enzymes ( n-ac-tcvc and n-ac-dcvc ) and further cleaved to reactive and mutagenic intermediates by mammalian and/or bacterial beta-lyase .
