Inhibition of Extracellular Enzymes Exposed to Cyanopeptides

CHIMIA, 2020
Harmful cyanobacterial blooms in freshwater ecosystems produce bioactive secondary metabolites including cyanopeptides that pose ecological and human health risks.

Molecular Characterization and Expression of the LAP3 Gene and Its Association with Growth Traits in the Blood Clam Tegillarca granosa

Fishes, 2021
Leucine aminopeptidase 3 (LAP3) is a metallopeptidase that cleaves N-terminal residues and is involved in protein maturation and degradation. In this study, we characterized the leucine aminopeptidase 3 (LAP3) gene from Tegillarca granosa (Tg-LAP3 for ...

Comprehensive Peptide Profiling Reveals the Influence of Streptococcus Thermophilus, Lactobacillus Delbrueckii Subsp. bulgaricus, and Endogenous Milk Proteases on the Hydrolysis of Milk Proteins During Early‐Stage Lactic Acid Fermentation

ChemFoodChem, EarlyView.
Untargeted peptide profiling investigates how S. thermophilus, Lb. bulgaricus, and endogenous milk enzymes impact proteolysis during early‐stage milk fermentation. ≥ 3000 identified peptides show the strongest influence of LB on the peptide profile and number of bioactive peptides. Shorter peptides are mostly formed by LB and hydrolyzed by ST.

An M29 Aminopeptidase from Listeria Monocytogenes Contributes to In Vitro Bacterial Growth but not to Intracellular Infection

Microorganisms, 2020
Aminopeptidases that catalyze the removal of N-terminal residues from polypeptides or proteins are crucial for physiological processes. Here, we explore the biological functions of an M29 family aminopeptidase II from Listeria monocytogenes (LmAmpII). We

A synthetic community promotes macadamia growth via root‐microbe interactions and systemic plant responses

iMetaOmics, EarlyView.
We employed an 18‐month pot experiment and an integrated multi‐omics approach to elucidate the potential mechanisms underlying synthetic community (SynCom)‐mediated macadamia growth promotion. SynCom inoculation enhanced soil nitrogen cycling and potential nutrient (e.g., iron) acquisition.

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 ...

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.

APRELIMINARY CHARACTERIZATION OF DIGESTIVE PROTEASE IN THE MID-GUT OF THE THIRD LARVAL INSTAR OF GASTEROPHILUS INTESTINALIS [PDF]

Veterinary Medical Journal - Giza, 2005
Protinases contained in the mid-gut of the early third instar of Gasterophilus intestinalis have been tentatively identified by midgut hydrolysis of synthetic substrates. Trypsin was identified by maximal hydrolysis of benzoyl-DL-arginine-p-nitroanilide (

Environmental Filtering and Microbial Interactions Drive Soil Bacterial and Fungal Community Assembly in Subtropical Forests

Land Degradation &Development, EarlyView.
ABSTRACT Soil microbial communities are pivotal to forest ecosystem functions, yet the mechanisms shaping their assembly across complex environments remain poorly understood. This study examined bacterial and fungal communities within topsoil and subsoil under subtropical coniferous forest (CF), mixed conifer–broadleaf forest (MF), and broadleaf forest
