Merck, 164598-50U, Aminopeptidase M, Porcine Kidney

General description
Aminopeptidase M (APM) is abundantly found in brush border membranes of the kidney, small intestine, placenta, and liver. It is a type II integral membrane protein, known as ectoenzyme.
Application
Aminopeptidase M, porcine kidney has been used:
to test and identify the peaks containing d-residue in the allatotropin-related peptide (ATRP)
to study its oxidative inactivation of enzyme activity, and to screen MIRA ingredients
for the proteolysis of isolevuglandins (IsoLGs) proteins

Biochem/physiol Actions
Aminopeptidase M (APM) is implicated in terminating the actions of certain neuropeptides, like the enkephalins and angiotensin III in the brain. It also metabolizes specific vasoactive peptides. It functions as a receptor for certain viruses, such as coronavirus 229E. APM is a nonspecific peptidase, which rapidly breaks down l-residue peptides.
Packaging
