In the first unambiguous demonstration of IZD interactions with a PTP other than PTP1B, it is shown by X-ray crystallography that the IZD motif binds within the catalytic site of the Yersinia pestis PTP YopH by similarly displacing a highly conserved water molecule. It is also shown that IZD-based bidentate ligands can inhibit YopH in a nonpromiscuous fashion at low micromolar concentrations. Hence, the IZD moiety may represent a useful starting point for the development of YopH inhibitors.
