Unraveling the 13C Hyperfine Structure of the 5‐Deazaflavin Radical in Solution Using Photo‐CIDNP Spectroscopy

open access: yesChemPhotoChem, Volume 10, Issue 6, June 2026.
The 13C hyperfine structure of the 5‐deazaflavin radical is elucidated by photo‐chemically induced dynamic nuclear polarization spectroscopy and compared to the flavin radical. Despite structural similarity to flavins, 5‐deazaflavins were long thought to act only as two‐electron transfer agents.

Studies on the Binding and Function of Flavin Phosphates with Flavin Mononucleotide-dependent Enzymes

open access: yesJournal of Biological Chemistry, 1966
Abstract The binding and function of FMN, 3,6,7-trimethyl-9-(1'-d-ribityl)isoalloxazine 5'-phosphate (3-methyl-FMN),6,7-dichloro-9-(1'-d-ribityl)isoalloxazine 5'-phosphate (6,7-dichloro-FMN), and 6,7-dimethyl-9-(5'-hydroxypentyl)isoalloxazine 5'-phosphate (5'-hydroxypentyl-FMN) has been investigated with reduced nicotinamide adenine dinucleotide ...

A Multiphysics Engineering Model of pH and Oxygen Transport Limitations in Textile‐Based Wearable Lactate Biosensors

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
A one‐dimensional multiphysics engineering model is developed to elucidate the coupled transport and reaction phenomena governing textile‐based wearable lactate biosensors operating in sweat. The model integrates diffusion of lactate, oxygen, hydrogen peroxide, and protons with dual‐substrate enzymatic kinetics, acid–base equilibria, and mediator‐based

ON A NEW FLAVIN MONONUCLEOTIDE PRODUCED BY RHIZOPUS ORYZAE

open access: yesTHE JOURNAL OF VITAMINOLOGY, 1963
1. As reported in the previous paper, the RF value of a new flavin mononucleotide, FMN′, in a solvent system of phenol-n-butanol-water (16:3:10) was 0.27, which is higher than that of FMN, 0.18, and lower than that of 4′, 5′-cyclic monophosphate, 0.50. It was further confirmed that FMN′ migrated faster than FMN toward the anode in paper electrophoresis.

Refractive Index Spectral Fingerprints of Pathogenic Bacteria Revealed by Monte Carlo‐Optimized Opto‐Microfluidic Extinction Spectroscopy

open access: yesJournal of Biophotonics, Volume 19, Issue 6, June 2026.
A physics‐informed opto‐microfluidic platform reconstructs refractive index spectra of pathogenic bacteria through Monte Carlo‐based inverse modeling. These optical fingerprints enable label‐free species identification with 97.75% accuracy using a one‐dimensional convolutional neural network, demonstrating a scalable biophotonic strategy for rapid ...

IR spectroscopic and quantum-chemical manifestation of flavin mononucleotide’s isoalloxazine ring protonation

open access: yesБіофізичний вісник, 2016
Flavin mononucleotide (FMN) is the prosthetic group of many oxidoreductases performing redox function in cells. The coenzyme reversible reduction reaction involvs isoalloxazine ring which may take two electrons and two protons upon reduction. The spectra

NADPH Dehydrogenase Gene Regulates Energy Distribution and Fatty Acid Metabolism During Fruiting Body Formation in the Filamentous Fungus Podospora anserina

open access: yesMicrobial Biotechnology, Volume 19, Issue 6, June 2026.
NADPH dehydrogenase gene deletion significantly triggered NADPH/NADP+ increase in mutant strains. NADPH gene deletion promoted Fatty acid biosynthesis and repressed β‐oxidation. NADPH gene deletion decreased oxidative phosphorylation and increased substrate‐level phosphorylation. Mutants exhibited hypersensitivity to oxidative stress, but promoted more

Coenzyme recognition and gene regulation by a flavin mononucleotide riboswitch [PDF]

open access: yesNature, 2009
The biosynthesis of several protein cofactors is subject to feedback regulation by riboswitches. Flavin mononucleotide (FMN)-specific riboswitches, also known as RFN elements, direct expression of bacterial genes involved in the biosynthesis and transport of riboflavin (vitamin B(2)) and related compounds.
