Structure of potato cathepsin D inhibitorStructure of potato cathepsin D inhibitor
Structural highlights
Function[API11_SOLTU] Inhibitor of cathepsin D (aspartic protease) and trypsin (serine protease). May protect the plant by inhibiting proteases of invading organisms. Publication Abstract from PubMedPotato cathepsin D inhibitor (PDI) is a glycoprotein of 188 amino acids which can inhibit both the aspartic protease cathepsin D and the serine protease trypsin. Here we report the first X-ray structure of PDI at a resolution of 2.1A showing that PDI adopts a beta-trefoil fold, which is typical of the Kunitz-family protease inhibitors, with the inhibitory loops protruding from the core. Possible reactive-site loops including one involving a unique disulphide and another involving a protruding 310 helix are identified and docking studies indicate the mode of action of this unusual bi-functional inhibitor.
