The stereospecificity of peptidyl prolyl cis/trans isomerases (PPIases) was studied using tetrapeptide substrate analogs in which one amino acid residue was replaced by the cognate D-amino acid in various positions of the peptide chain. Reversed stereocenters around proline markedly increased the rate of the spontaneous trans to cis isomerization of the prolyl bond whereas cis to trans isomerizations were less sensitive ...
