Reconstitution of Escherichia coli photolyase with flavins and flavin analogs
Biochemistry, 1990Escherichia coli DNA photolyase contains two chromophore cofactors, 1,5-dihydroflavin adenine dinucleotide (FADH2) and (5,10-methenyltetrahydrofolyl)polyglutamate (5,10-MTHF). A procedure was developed for reversible resolution of apophotolyase and its chromophores.

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.
