The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

open access: yesFEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

EFFECT OF SOIL POTASSIUM LEVELS AND DIFFERENT POTASSIUM FERTILIZERS ON YIELD, MACROELEMENT AND CHLORIDE NUTRION STATUS OF APPLE TREES IN FULL FRUITION PERIOD

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2011
The experiment was established in the spring 1999 on lessive soil developed from light boulder clay. Apple trees of Golden Delicious cv. on M.26 rootstock were planted in 3.5 × 1.2 m (2381 trees·ha-1) spacing. Research involved the effect of diversified

The C1 inhibitor potentiation by β-1,3-glucan sulfates depends on both degree of sulfation and molecular mass.

open access: yes, 2016
The C1s activity was measured in the presence of C1-INH and test compound (final concentration: a) 0.625 μg/ml b) 0.3125–0.625–1.25–6.25 μg/ml) by a chromogenic substrate assay. The C1-INH potentiation (%) is the increase in C1s inhibition in presence of

Characterization of the key membrane protein cytochrome Cyc2 from Ghiorsea bivora

open access: yesFEBS Open Bio, EarlyView.
This study reports the first detailed biochemical analysis of Cyc2TAG1_1, a cytochrome protein involved in microbial iron oxidation. We produced and purified this enzyme in E. coli, then measured its iron‐oxidizing efficiency, and characterized its electrical and structural properties.

Characterizing Cutaneous α‐Synuclein Deposition and Seeding Activity in Parkinson's Disease Subtypes

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cutaneous phosphorylated α‐synuclein (p‐syn) and α‐synuclein seeding activity are promising biomarkers for Parkinson's disease (PD), but their clinical value remains uncertain due to disease heterogeneity. This study evaluates these two biomarkers in PD patients to inform phenotype‐specific diagnosis and disease severity assessment ...

Cerebrospinal Fluid Over Plasma Links Analytes to Cognitive Decline in Older Adults at Risk for Alzheimer's Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To identify inflammatory analytes in cerebrospinal fluid (CSF) and plasma associated with cognitive decline in cognitively normal (CN) older adults at risk for Alzheimer's disease (AD). Methods In a longitudinal study of 118 CN older adults (65–80 years, 54% APOE ε4, 26% preclinical AD), 1331 CSF and 1501 plasma analytes were ...

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...
