Deazaflavin reductive photocatalysis involves excited semiquinone radicals

Nature Communications, 2020
Flavins and deazaflavins are well suited for photoredox processes but their application in photoreductions is challenging. Here, the authors provide direct evidence of the high reductive power of excited deazaflavin semiquinones and their application in ...

Synergistic Tuning of Conformational Dynamics, Electron Tunneling, and Substrate Positioning Enhances Electron Transfer in a P450 Chimera for Calcifediol Biosynthesis

Advanced Science, EarlyView.
A synergistic electron transfer (ET) optimization strategy modulating conformational dynamics, ET pathway, and substrate orientation is proposed for self‐sufficient cytochrome P450s. Guided by this strategy, a P450 variant with improved ET and catalytic efficiency was identified, and the underlying molecular basis was revealed by computational analysis.

FLAVIN-HYPOXANTHINE DINUCLEOTIDE

THE JOURNAL OF VITAMINOLOGY, 1957
1. FHD was synthesized from FAD by deamination with nitrous acid and the product was first isolated as barium salt. The yield and purity were, however, unsatisfactory by this method. Therefore, the product was extracted with cresol, followed by transfer in aqueous phase, and by subjecting to column chromatography, FHD was obtained in high purity in ...

Synthesis of rigidified flavin–guanidinium ion conjugates and investigation of their photocatalytic properties

Beilstein Journal of Organic Chemistry, 2009
Flavin chromophores can mediate redox reactions upon irradiation by blue light. In an attempt to increase their catalytic efficacy, flavin derivatives bearing a guanidinium ion as oxoanion binding site were prepared.

Metarhizium anisopliaeMitigates the Phytotoxicity of Lead and Nanoplastics on Rice by Modifying Physiological, Transcriptomic, Metabolomic Activities, and Soil Microbiome

Advanced Science, EarlyView.
Metarhizium anisopliae alleviates the phytotoxic effects of polyethylene nanoplastics (NP) and lead (Pb) in rice by decreasing Pb uptake, restoring antioxidant and hormonal equilibrium, and promoting growth. Additionally, the fungus modifies the rhizosphere microbiota, enhancing both contaminant tolerance and plant growth, thereby effectively ...

Reprogramming Listeria monocytogenes flavin metabolism to improve its therapeutic safety profile and broaden innate T-cell activation

mBio
Listeria monocytogenes is a facultative intracellular bacterial pathogen that is a potent inducer of cell-mediated immunity, which has led to the development of attenuated, Listeria-based cancer vaccines. L. monocytogenes strains, such as live-attenuated
