    Five renin inhibitors were cocrystallized with endothiapepsin, a fungal enzyme homologous to renin. Crystal structures of inhibitor-bound complexes have provided invaluable insight regarding the three-dimensional structure of the aspartic proteinase family of enzymes, as well as the steric and polar interactions that occur between the proteins and the bound ligands. Beyond this, subtleties of binding have been revealed, including multiple subsite binding modes and subsite interdependencies. This information has been applied in the design of novel potent renin inhibitors and in the understanding of structure-activity relationships and enzyme selectivities.
