Kinetics of diketopiperazine formation using model peptides
The intramolecular aminolysis of Phe-Pro-p-nitroaniline (Phe-Pro-pNA) to Phe-Pro-diketopiperazine (Phe-Pro-DKP) was studied as a function of pH, temperature, buffer concentration, and buffer species using an HPLC assay that permits simultaneous analysis o
