The Differing Roles of Flavins and Quinones in Extracellular Electron Transfer in Lactiplantibacillus plantarum

open access: yesbioRxiv, 2022
Lactic acid bacteria are named because of their nearly exclusive fermentative metabolism. Thus, the recent observation of EET activity—typically associated with anaerobic respiration—in this class of organisms has forced researchers to rethink the rules ...

Systematic Theoretical Study on the pH-Dependent Absorption and Fluorescence Spectra of Flavins

open access: yesMolecules, 2023
Flavins are a class of organic compounds with the basic structure of 7,8-dimethy-10-alkyl isoalloxazine. They are ubiquitous in nature and participate in many biochemical reactions. Due to various existing forms, there is a lack of systematic research on

Surface-Enhanced Raman Spectroscopic Analysis of Flavoenzyme Cofactors: Guidance for Flavin-Related Bio- and Chemo- Sensors

open access: yesChemosensors, 2023
Flavin mononucleotides (FMNs) and flavin adenine nucleotide (FAD) play vital roles in the electron-transfer processes in diverse enzymatic reactions.

Molecular Editing of Flavins for Catalysis

open access: yesSynthesis, 2021
The diverse activity of flavoenzymes in organic transformations has fascinated researchers for a long time. However, when applied outside an enzyme environment, the isolated flavin cofactor only shows largely reduced activity.

Reduced Molecular Flavins as Single-Electron Reductants after Photoexcitation.

open access: yesJournal of the American Chemical Society, 2021
Flavoenzymes mediate a multitude of chemical reactions and are catalytically active both in different oxidation states and in covalent adducts with reagents.

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.

Enhanced Solid-State Fluorescence of Flavin Derivatives by Incorporation in the Metal-Organic Frameworks MIL-53(Al) and MOF-5

open access: yesMolecules, 2023
The flavin derivatives 10-methyl-isoalloxazine (MIA) and 6-fluoro-10-methyl-isoalloxazine (6F-MIA) were incorporated in two alternative metal-organic frameworks, (MOFs) MIL-53(Al) and MOF-5.

Photodegradation of Riboflavin under Alkaline Conditions: What Can Gas-Phase Photolysis Tell Us about What Happens in Solution?

open access: yesMolecules, 2021
The application of electrospray ionisation mass spectrometry (ESI-MS) as a direct method for detecting reactive intermediates is a technique of developing importance in the routine monitoring of solution-phase reaction pathways.

Interplay of phosphate and carbonate ions with flavin photosensitizers in photodynamic inactivation of bacteria.

open access: yesPLoS ONE, 2021
Photodynamic inactivation (PDI) of pathogenic bacteria is a promising technology in different applications. Thereby, a photosensitizer (PS) absorbs visible light and transfers the energy to oxygen yielding reactive oxygen species (ROS).

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 a covalent bond between a flavin cofactor and its hosting protein. By using a flavin transferase and carving a flavinylation motif in target proteins, we demonstrate that ‘dissociable’ flavoproteins can be turned into covalent flavoproteins ...
