Biomarkers of oxidative stress, biochemical changes, and the activity of lysosomal enzymes in the livers of rainbow trout (Oncorhynchus mykiss Walbaum) vaccinated against yersiniosis before a Yersinia ruckeri challenge

Journal of Veterinary Research
This study aimed to evaluate biomarkers of oxidative stress (2-thiobarbituric acid reactive substances, aldehyde and ketone derivatives of oxidatively modified proteins and total antioxidant capacity), the activity of antioxidant enzymes (superoxide ...

Phosphonic Analogues of Phenylglycine as Inhibitors of Aminopeptidases: Comparison of Porcine Aminopeptidase N, Bovine Leucine Aminopeptidase and Aminopeptidase from Barley Seeds

, 2019
Inhibitory activity of 14 phosphonic analogues of phenylglycine, substituted in aromatic ring by fluorine and chlorine, was determined towards porcine aminopeptidase N. The obtained data served as a basis for studying their interaction with the enzyme as modelled by the use of Schrödinger Release 2018 program.

Tolerance to Phosphorus Deficiency Improves Seed Phytic Acid‐to‐Iron Molar Ratios in Common Bean

Plant, Cell &Environment, Volume 49, Issue 7, Page 4152-4165, July 2026.
ABSTRACT Although significant advances have been achieved in the biofortification of common beans to overcome deficiencies in Zinc (Zn) and iron (Fe), the mechanisms involved remain poorly understood. We thus explored the relationships between phosphorus nutrition and Zn and Fe accumulation in four bean genotypes (Edar, Nizok, Colorado and Chimbolos ...

Rapid CO2 effects on protein‐related metabolism during photosynthetic gas exchange

The Plant Journal, Volume 127, Issue 1, July 2026.
SUMMARY It is common practice to vary atmospheric CO2 mole fraction (Ca) during gas exchange experiments to manipulate photorespiration and explore photosynthetic properties such as maximum carboxylation velocity. In doing so, it is assumed that changing Ca essentially alters the carboxylation‐to‐oxygenation ratio, with negligible effects on other ...

Tissue-specific interactions between nuclear proteins and the aminopeptidase N promoter.

, 1991
Udgivelsesdato: 1991-Sep-25Aminopeptidase N/CD13 is a metallopeptidase found in many tissues. Aminopeptidase N activity is high in the small intestinal mucosa, moderate in the liver, and low in the spleen.

Role of intestinal brush border membrane aminopeptidase N in dipeptide transport

, 1984
The kinetics of uptake of radioactive label from [U-14C]Gly, L-[4,5-3H]Leu and the dipeptide [14C]Gly—L-[4,5-3H]Leu by the brush border membrane vesicles of porcine small intestine have been studied.

Evidence for an apical sorting signal on the ectodomain of human aminopeptidase N

, 1992
In polarized epithelial cells aminopeptidase N is targeted to the apical membrane. The aim of this study was to determine whether a sorting signal is necessary for its correct transport to the apical membrane and, if so, to localize this sorting signal ...

Discovery of Bioluminogenic Probes for Aminopeptidase N Imaging

, 2016
To find an approach that can image the hydrolysis activity of aminopeptidase N (APN) both in vitro and in vivo, three bioluminescent probes have been well designed and synthesized herein.
