Molecular complexes of flavins: A comparison of flavin-indole and flavin-phenol interactions
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1967Abstract 1. Molecular complex formation between flavins and indoles in neutral and acid solution has been studied. One to one complexes are formed, many of which can be isolated as crystalline solids. Visible spectra of complex solutions show more or less broadening of the flavin absorption and tailing into the long-wavelength region.

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

Calorimetric studies of flavin binding protein: Flavin analog binding
Archives of Biochemistry and Biophysics, 1983The effect of flavin structure variation upon the overall binding reaction of flavin to hen egg white riboflavin binding protein (WRBP) was correlated to thermodynamic parameters obtained via titration calorimetry. This effect was measured by determining a reference binding enthalpy (delta Href) for 3-carboxymethylriboflavin and subsequently comparing ...

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.

Polarography of flavine mononucleotide and flavine adenine dinucleotide
Archives of Biochemistry and Biophysics, 1957Abstract Flavine coenzymes FMN and FAD were studied polarographically. Both flavines show well-defined reversible polarographic waves consisting of a normal reduction wave and a “post” wave due to adsorption. The half-wave potentials of the normal reduction wave correspond to the standard oxidation-reduction potentials determined potentiometrically ...

Publisher Summary This chapter discusses the determination of flavine adenine dinucleotide (FAD) that depends on the specific reactivation of the apoenzyme of D-amino acid oxidase from pig kidney by this coenzyme. Comparison of the reactivation with a standard solution of FAD is necessary because the Michaelis constant of the enzyme for F AD varies ...
