Nitrogen Enrichment Enhances Soil Multifunctionality Through Distinct Drivers Across Urban, Suburban, and Rural Forests

Land Degradation &Development, EarlyView.
ABSTRACT The accelerating pace of urban expansion has profoundly reshaped urban–rural ecosystems, altering soil environments and impairing key ecological services. However, the combined impacts of urban expansion and atmospheric nitrogen (N) deposition on soil multifunctionality—the capacity to sustain multiple ecological processes—remain poorly ...

Aminopeptidases do not directly degrade tau protein

Molecular Neurodegeneration, 2010
Background Tau hyperphosphorylation and aggregation to form intracellular neurofibrillar tangles is prevalent in a number of tauopathies. Thus there is current interest in the mechanisms involved in Tau clearance. It was recently reported that Tau can be

Impact of ACE and Endoplasmic Reticulum Aminopeptidases Polymorphisms on COVID-19 Outcome

Diagnostics, 2023
Background: COVID-19 outcomes display multiple unexpected varieties, ranging from unnoticed symptomless infection to death, without any previous alarm or known aggravating factors. Aim: To appraise the impact of ACErs4291(A/T) and ERAP1rs26618(T/C) human

HISTOCHEMICAL DEMONSTRATION OF AMINOPEPTIDASE [PDF]

Journal of Histochemistry & Cytochemistry, 1956
A histochemical method for demonstration of aminopeptidase in tissue sections using the substrates l-leucyl β-naphthylamide and dl-alanyl β-naphthylamide is presented. The method may also be quantitated on tissue sections. The successful histochemical demonstration of the enzyme with both substrates is dependent upon the use of frozen-

Alpine Secondary Forest Types Influence Soil Microbial Community Structure and Enzyme Activities on the Eastern Qinghai–Tibet Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Soil microbial communities and enzyme activities influence soil functions and tree growth in ecologically fragile alpine regions. However, differences in soil microbial communities among secondary forests remain poorly understood in the Qinghai–Tibet Plateau.

Root Order Dependent Changes in Fine‐Root Substrate and Soil Environment Regulate Soil Organic Nitrogen Fractions Under Acid Rain and Nitrogen Deposition

Land Degradation &Development, EarlyView.
ABSTRACT Acid rain and nitrogen deposition are important environmental stressors affecting soil nitrogen cycling in subtropical forests, whereas fine‐root decomposition represents a major pathway for soil organic nitrogen (SON) input and transformation.

The Role of Aminopeptidase ERAP1 in Human Pathology—A Review

Current Issues in Molecular Biology
Aminopeptidases are a group of enzymatic proteins crucial for protein digestion, catalyzing the cleavage of amino acids at the N-terminus of peptides. Among them are ERAP1 (coding for endoplasmic reticulum aminopeptidase 1), ERAP2 (coding for endoplasmic

Carbon‐Fixing Bacterial Network Complexity Mediates Soil Multifunctionality in a Panax notoginseng‐Pinus armandii Agroforestry System

Land Degradation &Development, EarlyView.
ABSTRACT Autotrophic carbon‐fixing bacteria (CFB) are central contributors to soil carbon sequestration and biogeochemical carbon cycling in agroforestry ecosystems and can act as reliable biological indicators for evaluating agroforestry ecosystem sustainability.

Study on endogenous protease and protein degradation of dry-salted Decapterus maruadsi

CyTA - Journal of Food, 2018
Extensive proteolysis and formation of flavor substances occur during the processing of dry-salted fish due to the action of endogenous proteases. This study analyzed the evolution of the endogenous proteases and the relationship between endogenous ...
