GENOME-WIDE IDENTIFICATION OF RNA SENSORS IN PROKARYOTES AND EUKARYOTES
… class of eukaryotic RNA sensors that recognize vitamin B2 (FMN) to control gene expression. This collection of RNA sensors expands our understanding of RNA function in the cell and suggests that RNA based sensing and gene regulation is much more widespread than previously appreciated.

Pearl Millet Nutritional Quality and Fertilization of Sweet Corn in Senegal
… soluble protein, starch, sugars, amino acids or vitamin B2 content of grains among VPD-groups. Accumulation of these constituents of pearl millet grain appear to be genetically controlled and are probably not affected by late drought stress. However, differences were noted among genotypes as the …

Molekulare Analyse der Riboflavinsynthesegene von Bartonella henselae und Aufbau einer speziesspezifischen PCR unter Verwendung des ribC Gens
… Der Biosyntheseweg für Riboflavin (Vitamin B2) existiert bei Pflanzen und Bakterien, nicht aber bei Wirbeltieren. Da die Riboflavinsynthesegene innerhalb einer Bakterienspezies stark konserviert sind und beim Menschen nicht vorkommen, sollten sie sich gut zur Identifizierung …

Biochemical and synthetic chemical approaches to studying the biosynthesis and regulation of bacterial secondary metabolites
… the biosynthesis of RoF. RoF is the only known vitamin B2 analog, and as such has antibiotic activity against both Gram-positive and Gram-negative bacteria. It is biosynthesized from a vitamin B2 precursor via two major intermediates. RosB is a multifunctional enzyme that carries out a …

Targeted depletion of RibF, a putative bifunctional FAD synthetase/ flavokinase in Mycobacterium smegmatis using CRISPR interference
… gene in the mycobacterial riboflavin (RF; vitamin B2) biosynthetic pathway. Given the role of RF as a core component of the essential flavin cofactors, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD), it was hypothesized that silencing ribF would disrupt the biosynthesis …

Pathogenesis, presentation, and treatment of keratoconus within the United States
… Linking is a procedure where through riboflavin (vitamin B2) and UV-A light, collagen cross links can be induced within the corneal stroma. By linking the collagen polymers, it is theorized that this could permanently halt the progression of keratoconus. This treatment has been approved in Europe …

Studies of the nutritional quality of commercial ‘ready to eat‘ infant foods in the United Kingdom
… to be of concern. With regard to the analyses of vitamins, a novel assay for the simultaneous quantitative determination of riboflavin (B2) and pyridoxine (B6) has been developed. The method involves a mild hydrolysis step, extraction of the supernatant by centrifugation followed by quantitative …

Electrical current generation by wild type and mutant Shewanella strains
… electrochemical cell analytes is riboflavin (vitamin B2). It was also discovered that removing the medium surrounding an electrode biofilm caused current production from the electrochemical cell to decrease. Returning the filtered original medium, or adding anaerobic riboflavin resulted in the …

The Development and evaaluation of photo-antimicrobial isoalloxazine dyes towards infection control
… tricyclic isoalloxazine structure of riboflavin, vitamin B2. Photosensitisers were synthesised using similar strategies to the isoalloxazine for a number of reasons: e.g. photoactivity and capability of degradation. In order to investigate which photosensitisers gave the highest reactive oxygen …

Towards a Fundamental Understanding of Aqueous Organic Redox Flow Batteries – A Study of Degradation, Aggregation, and Reactivity
… biomolecule which is readily derived from vitamin B2. These findings were then used to improve performance dramatically. FMN hydrolysis products were identified via *in-situ* NMR and EPR, and it was shown that these products give rise to the additional plateau seen during charging of a …

Biofilm formation by Shewanella oneidensis MR-1 towards fundamental understanding of anode respiring communities
Microbial fuel cells are bioelectrochemical devices where, on the anode, microorganisms oxidize complex carbon sources and reduce the electrode via complex mechanisms of extra-cellular electron transfer (EET). To date, Geobacter sulfurreducens has been identified as producing not only the largest …
