Figure 7From: Structural definition and substrate specificity of the S28 protease family: the crystal structure of human prolylcarboxypeptidaseStructural comparison of DPP7 and PRCP. (A) Structural alignment of PRCP (blue) and DPP7 (yellow) and the sequence insertion of DPP7 that occludes the active-site cleft (red). (B) Enlarged view of site region with DPP7-specific insertion (red). Asp334 is shown as sticks.Back to article page
