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.

l- to d-residue isomerization is a post-translational modification (PTM) present in neuropeptides, peptide hormones, and peptide toxins from several animals. In most cases, the d-residue is critical for the biological function of the resulting d-amino acid-containing peptide (DAACP). Here, we

Isolevuglandins (IsoLGs) are a family of highly reactive 4-ketoaldehydes formed by lipid peroxidation that modify the lysyl residues of cellular proteins. Modification of proteins by IsoLGs have been shown to contribute to disease processes such as the development of hypertension.
