GO Classification
Functions
glutaminyl-peptide cyclotransferase activity / zinc ion binding
Processes
cellular protein modification process / peptidyl-pyroglutamic acid biosynthetic process, using glutaminyl-peptide cyclotransferase
Components
extracellular exosome
General Function
Zinc ion binding
Specific Function
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. Also catalyzes N-terminal pyroglutamate formation. In vitro, catalyzes pyroglutamate formation of N-terminally truncated form of APP amyloid-beta peptides [Glu-3]-beta-amyloid. May be involved in the N-terminal pyroglutamate formation of several amyloid-related plaque-forming peptides.
