Separation of Flavin and Phosphorylated Flavin [PDF]

Nature, 1938
Greene and Black1 have found that phenol, the cresols, aniline and benzyl-alcohol are suitable for the extraction of free flavin from water.

The plant growth promoting substance, lumichrome, mimics starch and ethylene-associated symbiotic responses in lotus and tomato roots

Frontiers in Plant Science, 2012
Symbiosis involves responses that maintain the plant host and symbiotic partner’s genetic program; yet these cues are far from elucidated. Here we describe the effects of lumichrome, a flavin identified from Rhizobium spp., applied to lotus (Lotus ...

The chemistry of flavines and flavoproteins. Photoreduction of flavines by amino acids [PDF]

Biochemical Journal, 1968
1. Flavines are photoreduced through their triplet states by amines and amino acids (e.g. EDTA and dl-phenylglycine). The anaerobic photoreduction of FMN and several other flavines with dl-phenylglycine was analysed in terms of a detailed kinetic scheme. 2. The reaction produces equimolar amounts of benzaldehyde, carbon dioxide and reduced flavine.

Multi-metal restriction by calprotectin impacts de novo flavin biosynthesis in Acinetobacter baumannii

Cell Chemical Biology, 2019
Summary Calprotectin (CP) inhibits bacterial viability through extracellular chelation of transition metals. However, how CP impacts general metabolism remains largely unexplored.

Flavin monooxygenase 3, the host hepatic enzyme in the metaorganismal trimethylamine N-oxide-generating pathway, modulates platelet responsiveness and thrombosis risk

Journal of Thrombosis and Haemostasis, 2018
Essentials Microbe‐dependent production of trimethylamine N‐oxide (TMAO) contributes to thrombosis risk. The impact of host flavin monooxygenase 3 (FMO3) modulation on platelet function is unknown.

Elongated Riboflavin‐Producing Shewanella oneidensis in a Hybrid Biofilm Boosts Extracellular Electron Transfer

Advanced Science, 2023
Shewanella oneidensis is able to carry out extracellular electron transfer (EET), although its EET efficiency is largely limited by low flavin concentrations, poor biofilm forming‐ability, and weak biofilm conductivity.

Structure-based electron-confurcation mechanism of the Ldh-EtfAB complex

eLife, 2022
Lactate oxidation with NAD+ as electron acceptor is a highly endergonic reaction. Some anaerobic bacteria overcome the energetic hurdle by flavin-based electron bifurcation/confurcation (FBEB/FBEC) using a lactate dehydrogenase (Ldh) in concert with the ...
