Insights into Metabolic Activity and Structure of the Retina through Multiphoton Fluorescence Lifetime Imaging Microscopy in Mice

open access: yesCells, 2022
Fluorescence lifetime imaging microscopy (FLIM) evaluates the metabolic state of tissue based on reduced nicotinamide adenine dinucleotide (NAD(P)H) and flavin adenine dinucleotide (FAD).

Time resolved fluorescence of flavin adenine dinucleotide [PDF]

open access: yesFEBS Letters, 1974
From a comparison of the quatum efficiencies and lifetimes of the isoalloxazine fluorescence in flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN) and from the slightly different extinction coefficients of both compounds Spencer and Weber have calculated and approximated the rate constants which describes the strong intramolecular ...

Azoreductase: a key player of xenobiotic metabolism

open access: yesBioresources and Bioprocessing, 2018
Azoreductases are diverse flavoenzymes widely present among microorganisms and higher eukaryotes. They are mainly involved in the biotransformation and detoxification of azo dyes, nitro-aromatic, and azoic drugs.

Stilbene compounds are specific inhibitors of the superoxide anion generation catalyzed by xanthine oxidase

open access: yesFood Chemistry: X, 2021
The inhibitory effect of xanthine oxidase (XO) reactions with stilbene compounds, 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging by stilbene compounds and superoxide anion (O2-) scavenging activity were examined.

Biophysical characterization of folded state type II luciferase‐like monooxygenase

open access: yesIndonesian Journal of Biotechnology, 2023
We noticed that the Priestia megaterium genome contains five Luciferase‐like monooxygenase (LLM) encoding genes, however, their functions are unknown. The objective of this work was to characterize the biophysical properties of the recombinant LLM2 from ...

Generation of the Camptothecin Scaffold by a Flavin‐Catalyzed Photooxidative Skeletal Reorganization

open access: yesAngewandte Chemie, EarlyView.
The biosynthetic pathway of the anticancer drug precursor camptothecin involves an enigmatic skeletal reorganization from a 6/5/6 tetrahydro‐β‐carboline to a 6/6/5 pyrroloquinoline ring system. Here, we show that this transformation can be achieved by photooxidation with flavin cofactors, such as flavin mononucleotide (FMN) as catalysts.

Flavin Catalysts in Organic Synthesis

open access: yesAngewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Direct wiring of redox cofactors onto gold electrodes via inorganic iron-sulfur clusters enhances charge transport

open access: yesBiosensors and Bioelectronics: X, 2022
Inorganic iron-sulfur clusters (Fe–S) have emerged as potential electrode anchors and electron shuttles for enzymatic biosensor systems involving nicotinamide adenine dinucleotide (NAD) cofactor.
