Glutaminyl cyclase Glutaminyl-tRNA cyclotransferase Glutamyl cyclase QPCT
Recombinant human Glutaminyl-peptide cyclotransferase protein (29-361AA)
ELISA, WB, IHC;Not yet tested in other applications.
Background / 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.
