Pyroglutamyl-peptide hydrolase (EC 3.4.11.8) removes the N-terminal pyroglutamyl residue from pyroglutamyl-containing peptides such as thyrotropin-releasing hormone (TRH), luteinizing hormone-releasing hormone (LH-RH), neurotensin, and bombesin. The aldehyde analogue of pyroglutamate, 5-oxoprolinal, was synthesized as an active site directed transition-state inhibitor of
