The nephrotoxicity and nephrocarcinogenicity of trichloroethylene ( TCE ) and tetrachloroethylene ( PCE ) are believed to be mediated primarily through the cysteine S - conjugate beta - lyase - dependent bioactivation of the corresponding cysteine S - conjugate metabolites S - ( 1 , 2 - dichlorovinyl ) - l - cysteine ( DCVC ) and S - ( 1 , 2 , 2 - trichlorovinyl ) - l - cysteine ( TCVC ) , respectively .
