The Regulatory Role of Quorum Sensing-Mediated Amino Acid Metabolism in Biofilm Formation and Motility of Hafnia alvei H4

Foods
The spoilage phenotype of microorganisms is a key mechanism leading to food spoilage, but how their metabolic environment affects the spoilage phenotype remains unclear. This study utilized metabolomics and spoilage phenotype analysis to reveal metabolic

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

Molecular Oncology, EarlyView.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

Serine-Based Cyclodepsipeptides on an Adamantane Building Block:  Design, Synthesis, and Characterization of a Novel Family of Macrocyclic Membrane Ion-Transporting Depsipeptides

, 2016
A simple two-step synthetic strategy provides a straightforward entry to a large variety of adamantane-containing serine-based cyclodepsipeptides. The design is flexible with respect to the choice of an amino acid, the ring size, and the nature of the ...

Enzymatic Phosphorylation of Serine

Journal of Biological Chemistry, 1972
Abstract The occurrence of a pyrophosphate:l-serine phosphotransferase in extracts of Propionibacterium shermanii is reported. A 102-fold purification, with 15% recovery, was obtained by successive use of protamine sulfate precipitation, acidification, ammonium sulfate precipitation, and chromatography on DEAE-cellulose and on Bio-Gel P-150 columns ...

Metabolic remodeling and immune evasion in glioblastoma: a focus on serine and lipid networks

Frontiers in Oncology
Glioblastoma (GBM) is a highly aggressive brain tumor characterized by metabolic plasticity that fuels growth, therapy resistance, and immune evasion. Among its reprogrammed pathways, serine and lipid metabolism play central roles.

Establishing an assay to evaluate d‐amino acid oxidase enzyme kinetics and inhibition using WST‐8 redox dye

FEBS Open Bio, EarlyView.
This study investigated a novel WST‐8‐based assay for evaluating d‐Amino acid oxidase (DAO) inhibitors. We confirmed its effectiveness using known inhibitors and found that uremic toxins possess relatively weak inhibitory activity compared to existing drugs.

Purification and characterization of novel fibrinolytic proteases as potential antithrombotic agents from earthworm Perionyx excavatus [PDF]

, 2011
Six protease fractions, namely FI, FII, FIII-1, FIII-2, FIII-3 and FIV, were isolated from Perionyx excavatus earthworm biomass by acetone precipitation, followed by serial chromatography using anion exchange, hydrophobic interaction and size exclusion ...

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

FEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

A yeast model of 5‐oxoproline accumulation reveals a general toleration to 5‐oxoproline

FEBS Open Bio, EarlyView.
Using a yeast model, we show that even high accumulation of 5‐oxoproline causes only mild cellular stress and does not trigger oxidative stress. Instead, cells adapt by activating efflux pumps and diverse protective pathways, suggesting that previously proposed harmful effects of 5‐oxoproline may arise from indirect metabolic imbalances rather than the

Ras signaling enhances the activity of C/EBPalpha to induce granulocytic differentiation by phosphorylation of serine 248 [PDF]

, 2003
The transcription factor C/EBPa regulates early steps of normal granulocyte differentiation since mice with a disruption of the C/EBPa gene do not express detectable levels of the G-CSF receptor and produce no neutrophils.
