Profiling of in vitro activities of urea-based inhibitors against cysteine synthases from Mycobacterium tuberculosis
CysK1 and CysK2 are two members of the cysteine/S-sulfocysteine synthase family in Mycobacterium tuberculosis, responsible for the de novo biosynthesis of L-cysteine, which is subsequently used as a building block for mycothiol. This metabolite is the first line defense of this pathogen against reactive oxygen and nitrogen species released by host macrophages after phagocytosis. In a previous medi
