Dose-dependent inhibition of wild-type and CCPGCC-insertion mutant PTPs. PTP activity of each wild-type and mutant was measured at the indicated FlAsH concentrations, and normalized to uninhibited (no-FlAsH) controls. Enzyme concentrations used were as follows: 100 nM for TCPTP and PTPH1; 200 nM for PTP1B, HePTP, and FAP-1; 500 nM for PTP-PEST; and 50 nM for PTPα.
