Responsible for the biosynthesis of pyroglutamyl peptides. Has a bias against acidic and tryptophan residues adjacent to the N-terminal glutaminyl residue and a lack of importance of chain length after the second residue (By similarity). Source: Recombinant protein corresponding to aa36-362 from mouse Glutaminyl-peptide cyclotransferase, fused to His-Tag at N-terminal, expressed in mammalian cell.
