Kinetic Isotope Effects Support the Twisted Amide Mechanism of Pin1 Peptidyl-Prolyl Isomerase

The Pin1 peptidyl-prolyl isomerase (PPIase) catalyzes isomerization of pSer/pThr-Pro motifs in regulating the cell cycle. Peptide substrates, Ac–Phe–Phe–phosphoSer–Pro–Arg–p-nitroaniline, were synthesized in unlabeled form, and with deuterium labeled Ser-d(3) and Pro-d(7) amino acids. Kinetic data w...
