Reduced Molecular Flavins as Single-Electron Reductants after Photoexcitation

open access: yesJournal of the American Chemical Society, 2022
Flavoenzymes mediate a multitude of chemical reactions and are catalytically active both in different oxidation states and in covalent adducts with reagents.

Expanding the chemical space of flavins with pentacyclic architecture. [PDF]

open access: yesNat Commun
Inspired by the prominent redox and optical properties of natural flavins, synthetic flavins have found broad applications in organic, photochemical, and biochemical research. Tailoring these properties of flavins, however, remains a challenge.

Flavins secreted by roots of iron‐deficient Beta vulgaris enable mining of ferric oxide via reductive mechanisms

open access: yesNew Phytologist, 2016
13 Pags.- 10 Figs.Iron (Fe) is abundant in soils but generally poorly soluble. Plants, with the exception of Graminaceae, take up Fe using an Fe(III)-chelate reductase coupled to an Fe(II) transporter.

Photo-CIDNP of Solvent-Exposed Flavins in Flavoproteins. [PDF]

open access: yesJ Phys Chem Lett
Photochemically induced dynamic nuclear polarization (photo-CIDNP) is a hyperpolarization NMR technique that enhances the resonances of molecules involved in the formation of spin-correlated radical pairs.

Fixing flavins: hijacking a flavin transferase for equipping flavoproteins with a covalent flavin cofactor

open access: yesJournal of the American Chemical Society, 2023
Most flavin-dependent enzymes contain a dissociable flavin cofactor. We present a new approach for installing in vivo a covalent bond between a flavin cofactor and its host protein. By using a flavin transferase and carving a flavinylation motif in target proteins, we demonstrate that "dissociable" flavoproteins can be turned into covalent ...

Natural Flavins: Occurrence, Role, and Noncanonical Chemistry [PDF]

open access: yes, 2021
Flavoproteins are of key importance to all life on earth for both primary and secondary metabolism. Most flavin-dependent enzymes utilize flavin mononucleotide (FMN) or flavin adenine dinucleotide (FAD) as redox cofactor for single-electron and hydride ...

Broadening the Scope of the Flavin‐Tag Method by Improving Flavin Incorporation and Incorporating Flavin Analogs

open access: yesChemBioChem, 2022
AbstractMethods for facile site‐selective modifications of proteins are in high demand. We have recently shown that a flavin transferase can be used for site‐specific covalent attachment of a chromo‐ and fluorogenic flavin (FMN) to any targeted protein. Although this Flavin‐tag method resulted in efficient labeling of proteins in vitro, labelling in E.

Flavin oxidation in flavin‐dependent N‐monooxygenases [PDF]

open access: yesProtein Science, 2018
AbstractSiderophore A (SidA) from Aspergillus fumigatus is a flavin‐containing monooxygenase that hydroxylates ornithine (Orn) at the amino group of the side chain. Lysine (Lys) also binds to the active site of SidA; however, hydroxylation is not efficient and H2O2 is the main product.

Regulation of the Flavin Redox Potential by Flavin‐Binding Antibodies [PDF]

open access: yesEuropean Journal of Biochemistry, 1997
Single‐chain Fv antibody fragments binding different flavin forms [10‐(5'‐carboxybutyl‐)flavin (Flox) and 10‐(5'‐carboxybutyl)‐1,5‐dihydroflavin (Flred)] have been generated from an antibody phage‐display library to study how a protein environment regulates the redox potential, starting from a protein other than a natural flavoprotein.
