Functional characterization of two M42 aminopeptidases erroneously annotated as cellulases. [PDF]

open access: yesPLoS ONE, 2012
Several aminopeptidases of the M42 family have been described as tetrahedral-shaped dodecameric (TET) aminopeptidases. A current hypothesis suggests that these enzymes are involved, along with the tricorn peptidase, in degrading peptides produced by the ...

Aminopeptidasic Enzymes as Early Biomarkers of Cardiac Surgery-Associated Acute Kidney Injury and Long-Term Events [PDF]

open access: yesBiomolecules
Background: Diagnosis of acute kidney injury (AKI) relies on serum creatinine (SCr) changes. This study investigated if urinary aminopeptidases are early and predictive biomarkers of cardiac surgery-associated AKI (CSA-AKI).

Phosphonic Acid Analogues of Phenylglycine as Inhibitors of Aminopeptidases: Comparison of Porcine Aminopeptidase N, Bovine Leucine Aminopeptidase, Tomato Acidic Leucine Aminopeptidase and Aminopeptidase from Barley Seeds [PDF]

open access: yesPharmaceuticals, 2019
The inhibitory activity of 14 racemic phosphonic acid analogs of phenylglycine, substituted in aromatic rings, towards porcine aminopeptidase N (pAPN) and barley seed aminopeptidase was determined experimentally.

Overlooked tools for studying soil nitrogen depolymerization: Aminopeptidase assays using nitroanilide substrates

open access: yesAgricultural & Environmental Letters, 2022
Aminopeptidases are one of the extracellular hydrolytic enzymes that catalyze organic nitrogen (N) depolymerization and are commonly assayed using fluorogenic substrates.

Technological Characterization of Lactic Acid Bacteria Strains for Potential Use in Cheese Manufacture

open access: yesFoods, 2023
A total of 26 lactic acid bacteria isolates from both Italian and Brazilian cheeses were tested for their use in cheesemaking. Isolates were screened for salt tolerance, exopolysaccharide and diacetyl production, lipolytic, acidifying, and proteolytic ...

Fingerprinting the substrate specificity of M1 and M17 aminopeptidases of human malaria, Plasmodium falciparum. [PDF]

open access: yesPLoS ONE, 2012
Plasmodium falciparum, the causative agent of human malaria, expresses two aminopeptidases, PfM1AAP and PfM17LAP, critical to generating a free amino acid pool used by the intraerythrocytic stage of the parasite for proteins synthesis, growth and ...

The Multifaceted Nature of Aminopeptidases ERAP1, ERAP2, and LNPEP: From Evolution to Disease

open access: yesFrontiers in Immunology, 2020
In the human genome, the aminopeptidases ERAP1, ERAP2 and LNPEP lie contiguously on chromosome 5. They share sequence homology, functions and associations with immune-mediated diseases.

Soil aminopeptidase activities under 145-year crop rotation and fertility practices in the North Central US

open access: yesGeoderma, 2023
Aminopeptidases catalyze the hydrolysis of peptides into constituent amino acids and are therefore a key step in nitrogen (N) depolymerization and downstream mineralization. Differences in carbon (C):N as well as sulfur (S) content of amino acids present
