| - | Tyrosine kinases and phosphatases establish the crucial balance of tyrosine phosphorylation in cellular signaling, but creating specific inhibitors of protein Tyr phosphatases (PTPs) remains a challenge. Here, we report the development of a potent, selective inhibitor of Mycobacterium tuberculosis PtpB, a bacterial PTP that is secreted into host cells where it disrupts unidentified signaling pathways. The inhibitor, (oxalylamino-methylene)-thiophene sulfonamide (OMTS), showed an IC(50) of 440 +/- 50 nM and >60-fold specificity for PtpB over six human PTPs. The 2 A resolution crystal structure of PtpB in complex with OMTS revealed a large rearrangement of the enzyme, with some residues shifting >27 A relative to the PtpB:PO(4) complex. Extensive contacts with the catalytic loop provide a potential basis for inhibitor selectivity. Two OMTS molecules bound adjacent to each other, raising the possibility of a second substrate phosphotyrosine binding site in PtpB. The PtpB:OMTS structure provides an unanticipated framework to guide inhibitor improvement. | ||
