Figure 8From: Structural definition and substrate specificity of the S28 protease family: the crystal structure of human prolylcarboxypeptidaseThe DPP7 substrate-binding groove is occluded by the DPP7-specific structural insertion. Views of PRCP (top) and DPP7 (bottom) showing the elongated, solvent-accessible substrate binding groove of PRCP (teal), and the binding site of DPP7 (teal) that is truncated by the DPP7-specific insert (red).Back to article page
