Protein

Glutaminyl-peptide cyclotransferase

Gene

QPCT

Organism
Bos taurus (Bovine)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

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 (By similarity).By similarity

Catalytic activityi

L-glutaminyl-peptide = 5-oxoprolyl-peptide + NH3.

Cofactori

Binds 1 zinc ion per subunit.By similarity
