-Proteases have a variety of strategies for selecting substrates in order, to prevent uncontrolled protein degradation. A recent crystal structure, determination of prolyl oligopeptidase has suggested a way for substrate, selection involving an unclosed seven-bladed beta-propeller domain. We, have engineered a disulfide bond between the first and seventh blades of, the propeller, which resulted in the loss of enzymatic activity. These, results provided direct evidence for a novel strategy of regulation in, which oscillating propeller blades act as a gating filter during, catalysis, letting small peptide substrates into the active site while, excluding large proteins to prevent accidental proteolysis.

+== Publication Abstract from PubMed ==
+Proteases have a variety of strategies for selecting substrates in order to prevent uncontrolled protein degradation. A recent crystal structure determination of prolyl oligopeptidase has suggested a way for substrate selection involving an unclosed seven-bladed beta-propeller domain. We have engineered a disulfide bond between the first and seventh blades of the propeller, which resulted in the loss of enzymatic activity. These results provided direct evidence for a novel strategy of regulation in which oscillating propeller blades act as a gating filter during catalysis, letting small peptide substrates into the active site while excluding large proteins to prevent accidental proteolysis.
