Although the target of BTZs has been identified as decaprenylphosphoryl-β-D-ribose 2'-epimerase (DprE1), their detailed mechanism of action remains obscure. Here we demonstrate that BTZs are activated in the bacterium by reduction of an essential nitro group to a nitroso derivative, which then specifically reacts with a cysteine residue in the active site of DprE1.GlutathioneResiduesArabinanBenzothiazinones: prodrugs that covalently modify the decaprenylphosphoryl-β-D-ribose 2'-epimerase DprE1 of Mycobacterium tuberculosistext::journal::journal article::research article
