Leucine aminopeptidase from Streptomyces hygroscopicus is controlled by a low molecular weight inhibitor

, 2002
In culture filtrate of Streptomyces hygroscopicus a producer of polyketide antibiotics, a leucine aminopeptidase and its autogenous inhibitor were detected.

Clay Minerals Change the Toxic Effect of Cadmium on the Activities of Leucine Aminopeptidase

Adsorption Science & Technology, 2021
Soil leucine aminopeptidase (LAP) is a hydrolytic enzyme involved in the acquisition of nitrogen by microorganisms. In contaminated soils, LAP activity is affected not only by the type and concentration of heavy metals but also by the form of enzyme ...

Storage treatment and diluent cause inconsistencies in commonly used fluorometric microplate enzyme assays conducted with saltmarsh soils

Limnology and Oceanography: Methods, EarlyView.
Abstract Fluorometric enzyme assays are a tool for determining potential enzyme activity in soils. A wide array of methodological approaches is adopted by different studies, making comparisons difficult. An important consideration is whether assay conditions replicate the environment of the samples or optimize potential enzyme activity.

Enzymological Review of Serum Leucine Aminopeptidase Isozymes [PDF]

, 1966
The serum of normal persons and patients of hepatobiliary disease showed hardly any difference in enzymological properties (degree of hydrolysis of substrate, attitude toward optinum pH, MnCl2, MgCl2, and EDTA) between fractions having leucine ...

Proteomic Analysis of Mixed Cell Membrane Extracts From Triple‐Negative Breast Cancer Cell Lines Revealed Broad Metabolic Reprogramming Associated With Tumor Progression

PROTEOMICS, EarlyView.
ABSTRACT Triple‐negative breast cancer (TNBC) represents the most aggressive subtype with limited therapeutic options and the poorest clinical outcomes. Using high‐resolution nUPLC‐QTOF‐MS/MS, we performed comprehensive proteomic profiling of TNBC cell lines representing disease progression stages: HCC‐1937 (stage IIB), HCC‐1599 (stage IIIA), and MDA ...

Changes in the Levels of Neuropeptides and Their Metabolizing Enzymes in the Brain Regions of Nucleus Basalis Magnocellularis-Lesioned Rats

Journal of Pharmacological Sciences, 2003
The regulation mechanism of the interrelation between neuropeptides and their metabolizing enzymes in in vivo tissues is still not clear. In the present report, we attempted to measure the levels of neuropeptides and their enzymes in the frontal cortex ...

The tomato chloroplast stromal proteome compendium elucidated by leveraging a plastid protein-localization prediction Atlas

Frontiers in Plant Science, 2023
Tomato (Solanum lycopersicum) is a model species for studying fruit development, wounding, herbivory, and pathogen attack. Despite tomato’s world-wide economic importance and the role of chloroplasts as metabolic hubs and integrators of environmental ...

Goose herbivory alters soil microbial community functional potential in a sub‐Arctic wetland

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivory alters below‐ground resource dynamics via direct and indirect mechanisms, yet its effects on microbial functional potential remain poorly understood. This limits our understanding of the mechanisms that link animal, plant and microbial functional roles in ...

Plant invasion in mountain ecosystems reduces soil micro‐food web complexity at higher elevations

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Anthropogenic activities have accelerated plant invasions in mountain ecosystems, impacting the structure and functions of native plant communities. Changes in above‐ground vegetation can drive shifts in below‐ground biota, yet the effects of plant invasions on soil ...
