Two Key Ferredoxins for Nitrogen Fixation Have Different Specificities and Biophysical Properties

Chemistry – A European Journal, Volume 31, Issue 37, July 2, 2025.
Two ferredoxins, FdC and FdN, are collectively essential for the process of nitrogen fixation by the iron nitrogenase in R. capsulatus. We explore the biophysical factors, through spectroscopic and structural characterizations, which determine ferredoxin functionality and pathway specificity. The structure of FdC (PDB: 9I2A) and model of FdN (AF‐D5ARY6)

Expanding the Phenotypic Spectrum of Methylenetetrahydrofolate Reductase (MTHFR) Deficiency in Childhood: A Case Series

Clinical Case Reports, Volume 13, Issue 7, July 2025.
ABSTRACT Methylenetetrahydrofolate reductase (MTHFR) deficiency is a rare inborn error of folate metabolism. A number of phenotypic findings have been identified to date, and we hereby wish to expand its phenotype based on our Irish experience of the condition.

Hyperhomocysteinemia‐Driven Ischemic Stroke: Unraveling Molecular Mechanisms and Therapeutic Horizons

Food Science &Nutrition, Volume 13, Issue 7, July 2025.
Neurotoxicity of Hcy. (A figure that best represents the scope of the paper.) Homocysteine can reduce the tightness of endothelial cell connections, increase vascular permeability, and damage the blood–brain barrier. Homocysteine activates various glutamate receptors on the surfaces of neurons and glial cells, triggering excitotoxicity, promoting the ...
