UniProtKB - Q8BH73 (QPCTL_MOUSE)
Protein
Glutaminyl-peptide cyclotransferase-like protein
Gene
Qpctl
Organism
Mus musculus (Mouse)
Status
Functioni
Responsible for the biosynthesis of pyroglutamyl peptides.By similarity
Caution
It is unclear whether this protein requires a metal cofactor for catalysis. It was originally proposed to be a Zn2+-dependent metalloenzyme based on structural similarities to bacterial aminopeptidases and the observation that it can bind Zn2+ ions, typically in a 1:1 stoichiometry (By similarity). However, a recent study suggests a Zn2+-independent catalytic mechanism (By similarity).By similarity
