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. Also catalyzes N-terminal pyroglutamate formation. In vitro, catalyzes pyroglutamate formation of N-terminally truncated form of APP amyloid-beta peptides [Glu-3]-amyloid-beta. May be involved in the N-terminal pyroglutamate formation of several amyloid-related plaque-forming peptides. {ECO:0000269|PubMed:15063747, ECO:0000269|PubMed:18486145, ECO:0000269|PubMed:21288892}. |Peptidase M28| |glutaminyl-peptide cyclotransferase activity| |peptidyl-pyroglutamic acid biosynthetic process, using glutaminyl-peptide cyclotransferase| |peptidyl-glutamine modification| |tertiary granule lumen| |specific granule lumen| |ficolin-1-rich granule lumen| |neutrophil degranulation| |neutrophil activation involved in immune response| |neutrophil mediated immunity| |neutrophil activation| |granulocyte activation| |leukocyte degranulation| |myeloid leukocyte mediated immunity| |myeloid cell activation involved in immune response| |myeloid leukocyte activation| |leukocyte activation involved in immune response| |cell activation involved in immune response| |regulated exocytosis| |leukocyte mediated immunity| |exocytosis| |zinc ion binding| |peptidyl-amino acid modification| |leukocyte activation| |secretion by cell| |export from cell| |cell activation| |immune effector process| |secretion| |immune response| |extracellular region| |vesicle-mediated transport| \\ === CRISPR Data === No hits were found.
