Biochemical establishment and characterization of EncM's flavin-N5-oxide cofactor
Journal of the American Chemical Society, 2015 The ubiquitous flavin-dependent monooxygenases commonly catalyze oxygenation reactions by means of a transient C4a-peroxyflavin. A recent study, however, suggested an unprecedented flavin-oxygenating species - proposed as the flavin-N5-oxide (FlN5[O ...

Chemical Communications, 2015 A new application of flavin derivatives in visible light photocatalysis was found. 1-Butyl-7,8-dimethoxy-3-methylalloxazine, when irradiated by visible light, was shown to allow an efficient cyclobutane ring formation via an intramolecular [2+2 ...

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 ...

Angewandte Chemie International Edition, EarlyView.CYB5R3 is identified as a putative electron‐transfer partner of viperin (RSAD2), explaining why ER localisation is required for antiviral activity. Its utilisation enabled the engineering of immune‐silent, catalytically self‐sufficient antiviral restriction factor enzymes (iCAREs) that produce an antiviral nucleoside triphosphate analogue (ANTA ...

Disulfide Bond–Modified Proteomics Reveals the Effects of Riboflavin on Protein Folding Dynamics
Animal Research and One Health, EarlyView.Riboflavin deficiency impairs oxidative protein folding, causing ER misfolded protein accumulation, CHOP activation, and apoptosis, revealing a role of riboflavin in proteostasis. ABSTRACT Riboflavin is a crucial micronutrient essential for maintaining cellular homeostasis, acting as an important precursor for flavoproteins that utilize flavin ...

Flavin Electron Shuttles Dominate Extracellular Electron Transfer by Shewanella oneidensis
mBio, 2013 Shewanella oneidensis strain MR-1 is widely studied for its ability to respire a diverse array of soluble and insoluble electron acceptors. The ability to breathe insoluble substrates is defined as extracellular electron transfer and can occur via direct
