QPCT, Mouse (His)

The QPCT protein plays a key role in pyroglutamyl peptide biosynthesis and exhibits substrate preference for N-terminal glutamine residues while showing specificity for residues near the N-terminus. Notably, its catalytic activity is independent of chain length beyond the second residue, emphasizing the importance of QPCT in the precise biosynthesis of pyroglutamyl peptides with diverse N-termini, contributing to various biological background. QPCT Protein, Mouse (His) is the recombinant mouse-derived QPCT protein, expressed by E. coli , with N-6*His tag.
