Figure 3.
Small molecule ligand or water is identified at the active site of LMW-PTP. Unbiased Fo-Fc difference map of (A) MES, (B) Compound 7, (C) Compound 9, and (D) three waters contoured at +3σ level is shown in green mesh. Small molecules are shown in stick (carbon in cyan), waters are shown in sphere, and the catalytic Cys12 and Arg18 in LMW-PTP are shown in stick (carbon in gray).
