Preparation and Storage

Background: Glutaminyl-peptide Cyclotransferase/QPCT

Glutaminyl-peptide Cyclotransferase, also known as Glutaminyl Cyclase, catalyzes the conversion of N‑terminal L-glutaminyl residues of peptides to pyroglutamyl groups (1). The enzyme is present in the pituitary and adrenal glands, where it is important for the generation of the N‑terminal pyroglutamyl groups of peptide hormones such as neurotensin and thyrotropin-releasing hormone. Glutaminyl Cyclase also catalyzes the conversion of N‑terminal L‑glutamyl residues to pyroglutamyl residues (2). This activity may contribute to the formation of several amyloid-related plaque forming peptides, contributing to Alzheimer’s disease pathology. Glutaminyl Cyclase is also considered to be a diagnostic marker of thyroid tumors (3).
