OSPREY is a suite of programs for computational structure-based protein design. OSPREY is developed in the lab of Prof. Bruce Donald at Duke University. Citations to the primary papers for our work can be found here.
OSPREY is specifically designed to identify protein mutants that possess desired target properties (e.g., improved stability, switch of substrate specificity, etc.). OSPREY can also be used for predicting small-molecule drug inhibitors. Starting with version 2.0, OSPREY can now design protein-protein and protein-peptide interactions.
