Bioactivation of S-(2,2-Dihalo-1,1-difluoroethyl)-l- cysteines and S-(Trihalovinyl)-l-cysteines by Cysteine S-Conjugate β-Lyase: Indications for Formation of both Thionoacylating Species and Thiiranes as Reactive Intermediates

Abstract
The covalent binding of reactive intermediates, formed by β-elimination of cysteine S-conjugates of halogenated alkenes, to nucleophiles was studied usin
