Application
Proline specific endopeptidase is useful for the determination of amino acid sequences of peptides and proteins containing proline residues. Proline specific endopeptidases may be useful in cancer, neurology and diabetes research . Prolyl endopeptidase (PEP) may be used as a drug target for neuropsychiatric diseases such as stress disorder, depression, and schizophrenia .
Biochem/physiol Actions
An endopeptidase is a proteolytic peptidase that breaks peptide bonds of nonterminal amino acids. Product E1411 is specific for proline (Pro). The Prolyl endopeptidase (PEP) mechanism is thought to be an induced fit mechanism, where the native enzyme exists in a conformationally flexible opened state but is changed to a closed state upon substrate binding .
Physical form
White amorphous lyophilized powder
