Glutaminyl-peptide cyclotransferase is an enzyme that in humans is encoded by the QPCT gene.

This gene encodes the human glutaminyl adenylate cyclase pituitary gland, which is responsible for the presence of pyroglutamyl residues in many neuroendocrine peptides. Amino acid sequence of this enzyme is 86% identical to the bovine glutaminyl cyclase.
