Figure 4: Difference Woods plot of active-site and allosteric inhibitors relative to apo PTP1B.

Difference in %deuteration values at 30 seconds in each inhibitor-bound state minus the apo PTP1B state, plotted against amino acid sequence. Blue lines indicate a difference interval of ± 5%.
A. Active-site inhibitor, TCS401.
B. Allosteric inhibitor, BB3.
