A flavin-based extracellular electron transfer mechanism in diverse gram-positive bacteria

open access: yesNature, 2018
Extracellular electron transfer (EET) describes microbial bioelectrochemical processes in which electrons are transferred from the cytosol to the exterior of the cell1.

Flavin Conjugated Polydopamine Nanoparticles Displaying Light-Driven Monooxygenase Activity

open access: yesFrontiers in Chemistry, 2019
A hybrid of flavin and polydopamine (PDA) has been explored as a photocatalyst, drawing inspiration from natural flavoenzymes. Light-driven monoxygenase activity has been demonstrated through the oxidation of indole under blue light irradiation in ...

Oxygen tension and riboflavin gradients cooperatively regulate the migration of Shewanella oneidensis MR-1 revealed by a hydrogel-based microfluidic device

open access: yesFrontiers in Microbiology, 2016
Shewanella oneidensis (S. oneidensis) is a model bacterial strain for studies of bioelectrochemical systems (BESs). It has two extracellular electron transfer pathways: 1) shuttling electrons via an excreted mediator riboflavin; and 2) direct contact ...

A proposal for a dipole-generated BLUF domain mechanism

open access: yesFrontiers in Molecular Biosciences, 2015
The resting and signaling structures of the blue-light sensing using flavin (BLUF) photoreceptor domains are still controversially debated due to differences in the molecular models obtained by crystal and NMR structures.

N5 Is the New C4a: Biochemical Functionalization of Reduced Flavins at the N5 Position

open access: yesFrontiers in Molecular Biosciences, 2020
For three decades the C4a-position of reduced flavins was the known site for covalency within flavoenzymes. The reactivity of this position of the reduced isoalloxazine ring with the dioxygen ground-state triplet established the C4a as a site capable of ...

Asymmetric Redox-Neutral Radical Cyclization Catalyzed by Flavin-Dependent ‘Ene’-Reductases

open access: yesNature Chemistry, 2019
Flavin-dependent ‘ene’-reductases (EREDs) are exquisite catalysts for effecting stereoselective reductions. Although these reactions typically proceed through a hydride transfer mechanism, we recently found that EREDs can also catalyse reductive ...

Electrochemistry Broadens the Scope of Flavin Photocatalysis: Photoelectrocatalytic Oxidation of Unactivated Alcohols

open access: yesAngewandte Chemie, 2019
Riboflavin-derived photocatalysts have been extensively studied in the context of alcohol oxidation. However, to date, the scope of this catalytic methodology has been limited to benzyl alcohols.

Effects of Flavin-Goethite Interaction on Goethite Reduction by Shewanella decolorationis S12

open access: yesFrontiers in Microbiology, 2019
Flavin mononucleotide (FMN) and riboflavin are structurally similar flavins, except for the presence of a phosphate group on the FMN molecule. They are used by a variety of electroactive bacteria as extracellular electron shuttles in microbial Fe ...

Time-resolved infrared difference spectroscopy in cells: Response of the basic region leucine zipper of aureochrome

open access: yesFrontiers in Physics, 2023
Aureochromes are light, oxygen, voltage (LOV) proteins and central blue-light receptors in algae acting as light-gated transcription factors. The C-terminal LOV domain mediates blue-light recognition and the basic region leucine zipper (bZIP) domain ...
