Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

Advanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

Trypanosoma brucei brucei:uptake and metabolism of pyridoxine and pyridoxal

, 1995
The uptake and metabolism of the B6 vitamers pyridoxine and pyridoxal by T. brucei (TREU 55) was investigated. The results show that these vitamers are taken up by simple diffusion followed by metabolic trapping.

Virtual Screening of Leishmanial Pyridoxal Kinase Enzyme Inhibitors by Repurposed Anti-Trypanosomal Libraries Reveals Two Core Scaffolds

, 2020
Leishmania is an intracellular protozoal infection, and it is classified as a neglected disease by the World Health Organization (WHO). Annually more than 2 million newly diagnosed cases were treated with highly toxic drugs.

Spontaneous Non‐Catalyzed Molecular Reactions and Interactions in the Human Body: Biomedical Implications

Advanced Science, EarlyView.
ABSTRACT The human body functions as a natural reactor for a vast network of chemical and biological reactions and physical interactions among small molecules, proteins, cells, and numerous other components. These reactions/interactions are essential for maintaining normal physiological functions.

Synthesis of [13C3]-B6 Vitamers Labelled at Three Consecutive Positions Starting from [13C3]-Propionic Acid

Molecules, 2018
[13C3]-labelled vitamers (PN, PL and PM) of the B6 group were prepared starting from [13C3]-propionic acid. [13C3]-PN was synthesized in ten linear steps with an overall yield of 17%.

Crystal structure of pyridoxal kinase from the Escherichia coli pdxK gene: Implications for the classification of pyridoxal kinases

, 2006
The pdrK and pdxY genes have been found to code for pyridoxal kinases, enzymes involved in the pyridoxal phosphate salvage pathway. Two pyridoxal kinase structures have recently been published, including Escherichia coli pyridoxal kinase 2 (ePL kinase 2)

Electroenzymatic CO2 Fixation

Angewandte Chemie International Edition, EarlyView.
Electroenzymatic CO2 fixation enables energy‐efficient, highly selective synthesis of complex molecules. Unlocking its full potential requires fundamental understanding of electrode‐coupled reductases and carboxylases. This review critically discusses available enzymes, product scope, and key thermodynamic and kinetic considerations, highlighting ...
