Effects of Flavin Monosulphate and Flavin Adenine Dinucleotide on the Electroencephalogram
Nature, 1958FLAVIN MONOSULPHATE (riboflavin-5′-monosulphate) has been found to inhibit D-amino-acid oxidase in competition with flavin adenine dinucleotide1. On the other hand, it was supposed that flavin adenine dinucleotide might have some important role in the brain since it reversed the inhibitory action of chlorpromazine on the oxidation of amino-acids by a ...

Flavin transferase: the maturation factor of flavin-containing oxidoreductases
Biochemical Society Transactions, 2018Flavins, cofactors of many enzymes, are often covalently linked to these enzymes; for instance, flavin adenine mononucleotide (FMN) can form a covalent bond through either its phosphate or isoalloxazine group. The prevailing view had long been that all types of covalent attachment of flavins occur as autocatalytic reactions; however, in 2013, the first

The oxidation of mercaptans by flavins
Tetrahedron Letters, 1969The reactions of flavins (isoalloxazines) with organic molecules are of interest as possible model systems for the catalytic reactions of vitamin B2 (riboflavin) requiring proteins. The flavoenzyme lipoic acid oxidase catalyzes the oxidation of dihydrolipoic acid (6,8-dimercaptoctanoic acid) to lipoic acid, 3-(6-valeryl)-1,2_dithiolane, and other ...

Flavines in experimental diabetes
Experientia, 1955Gli autori hanno determinato il FAD e la frazione FMN + Rib. nel fegato di ratti normali e diabetici da allossana. Il FAD e stato trovato diminuito in modo significativo nei diabetici. Somministrando riboflavina + ATP si ottiene un aumento dei valori del FAD. Questi valori restano quasi immutati somministrando riboflavina da sola.

Flavin-dependent dehalogenases
2020Flavin-dependent dehalogenases use flavin as a cofactor to catalyze carbon-halogen (C-X) bond cleavage from halogenated compounds which are mainly distributed as persistent environmental pollutants via anthropogenic activities. The accumulation of these compounds results in adaptation of bacteria to evolve metabolic pathways to metabolize the agents ...

Bacterial Flavin Mononucleotide Riboswitches as Targets for Flavin Analogs
2013Roseoflavin is a toxic riboflavin (vitamin B2) analog and naturally is produced by Streptomyces davawensis. Roseoflavin is converted to roseoflavin mononucleotide (RoFMN) by promiscuous flavokinases (EC 2.7.1.26). Flavin mononucleotide (FMN) riboswitches control the expression of genes involved in riboflavin biosynthesis and/or transport.

Photodynamics of pyrene-flavin and phenothiazine-flavin dyads
SPIE Proceedings, 2007A pyrene-flavin (isoalloxazine) dyad (PFD) and a phenothiazine-phenylene-isoalloxazine dyad (PPF), dissolved in dichloromethane are characterized by absorption and emission spectroscopy. These dyads are model compounds for flavin based blue-light photoreceptors.

Synthesis and Properties of Flavin Ribofuranosides and Flavin Ribopyranosides
Helvetica Chimica Acta, 2000Ribose-containing coenzymes like flavin mononucleotide (FMN) can be considered to be fossils of a prebiotic RNA world in which RNA encoded genetic information and catalyzed chemical reactions. To investigate the catalytic and base-pairing properties of FMN-containing oligonucleotides, the two cyclic flavin β-D-ribosides 3 and 4 derived from riboflavin ...

The acceptor specificity of flavins and flavoproteins. II. Free flavins
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 19711. For comparison with flavoprotein oxidases, a study has been made of free flavins in the reduced form with respect to the specificity and stoichiometry of their oxidation by a series of acceptors. 2. Reduced flavins uncombined with proteins show very little acceptor specificity and react very rapidly with nearly all the commonly used acceptors ...
