Two enantiomeric candidate molecules were predicted to bind with high potency (with R isomer binding stronger than S), but in two distinct conformations. The experiments verified that computational predictions concerning the binding affinities and the binding modes were correct for both isomers. The designed R isomer is the best-known inhibitor (K-d similar to 30 pM) of human carbonic anhydrase II.en-USJournal Article2019-10-1110.1073/pnas.032673399
