Glutaminyl-peptide Cyclotransferase/QPCT Products

Glutaminyl-peptide Cyclotransferase, also known as Glutaminyl Cyclase, catalyzes the conversion of N-terminal L-glutaminyl residues of peptides to pyroglutamyl groups. 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 a...
