Prolyl Endopeptidase (PREP)

Prolyl endopeptidase (PREP) inhibitors target a serine protease that cuts short peptides after proline. The cytosolic enzyme is also known in the literature as prolyl oligopeptidase (POP). A seven-bladed beta-propeller domain covers the catalytic site and admits only peptides of about 30 residues or fewer. Reported substrates include neuropeptides such as substance P, arginine vasopressin and thyrotropin-releasing hormone. PREP also binds alpha-synuclein, and KYP-2047 lowers alpha-synuclein aggregates in cell and mouse models of Parkinson's disease. Next to inhibitors such as KYP-2047, Y-29794 oxalate and SUAM 1221, the section lists the chromogenic p-nitroanilide (pNA) substrates Z-Gly-Pro-pNA and Suc-Ala-Pro-pNA for activity assays.

    Suc-Ala-Pro-pNA

    Suc-Ala-Pro-pNA is a specific substrate for prolyl endopeptidase (PEP), designed to facilitate the measurement of PEP activity and stability. This peptide substrate releases para-nitroaniline (pNA) upon hydrolysis, enabling quantification in various experimental settings. It is valuable for biochemical assays and research focused on proteolytic enzyme activity, particularly in the context of neurodegenerative diseases and other related disorders.
