Reimagining Lignin Valorization: Synthetic Biology–Enabled Sustainable Aromatic Carbon Biomanufacturing

open access: yesAdvanced Science, EarlyView.
The diagram illustrates a sustainable model of lignin valorization and carbon cycling based on microbial cell factories. Using lignin as the feedstock, synthetic biology technologies, including depolymerization, cell factory construction, pathway gene module integration, and metabolic network regulation, are applied to convert lignin into bulk ...

Synthesis of rigidified flavin–guanidinium ion conjugates and investigation of their photocatalytic properties

open access: yesBeilstein Journal of Organic Chemistry, 2009
Flavin chromophores can mediate redox reactions upon irradiation by blue light. In an attempt to increase their catalytic efficacy, flavin derivatives bearing a guanidinium ion as oxoanion binding site were prepared.

Engineering‐Modulated Molybdenum Enzymes Strategy for Tumor‐Specific Metabolic‐Immunotherapy

open access: yesAdvanced Science, EarlyView.
Biodegradable molybdenum sulfide nanoparticles were synthesized via a one‐pot strategy to increase molybdenum enzyme activity and thus effectively potentiate anti‐tumor immunity by integrating molybdenum‐based metalloimmunotherapy with hydrogen sulfide gas therapy.

UbiX is a flavin prenyltransferase required for bacterial ubiquinone biosynthesis

open access: yesNature, 2015
Ubiquinone (also known as coenzyme Q) is a ubiquitous lipid-soluble redox cofactor that is an essential component of electron transfer chains. Eleven genes have been implicated in bacterial ubiquinone biosynthesis, including ubiX and ubiD, which are ...

Cell Non-Autonomous Activation of Flavin-containing Monooxygenase Promotes Longevity and Healthspan

open access: yesScience, 2015
Aging: All in the head—and the gut The effects of hypoxia and caloric restriction, both of which extend life span in Caenorhabditis elegans, converge on the activation of an enzyme in cells of the intestine. Leiser et al.

Stimuli-Responsive Luminescence of an Amphiphilic Flavin Derivative via Thermodynamic and Kinetic Aggregation in Water

open access: yesPhotochem
In this study, we investigated environmentally responsive photoluminescence color changes in water using an amphiphilic flavin derivative (1a) functionalized with an alkylsulfonate group.

Entdeckung eines antiviralen Elektronentransferprozesses zur Erzeugung katalytisch selbstversorgender viraler Restriktionsfaktoren

open access: yesAngewandte Chemie, EarlyView.
CYB5R3 wird als mutmaßlicher Elektronentransferpartner von Viperin (RSAD2) identifiziert, was erklärt, warum die ER‐Lokalisation für die antivirale Aktivität erforderlich ist. Dieses Wissen ermöglichte die Entwicklung immunstiller, katalytisch selbstversorgender antiviraler Restriktionsfaktor‐Enzyme (iCAREs), die ein antivirales Nukleosidtriphosphat ...

C5-alkyl and C5-aryl Substituted 5-Deazaflavin as Sensitizers for Photodehalogenation of Aryl Halides

open access: yesMolecules
Aryl halides are important intermediates for chemical synthesis. However, the negative reduction potential up to −2.7 V (vs. SCE) makes photoredox conversion of aryl halides by reductive dehalogenation to aryl radicals for chemical transformations ...

Crystal Structure of the Apo-Form of NADPH-Dependent Thioredoxin Reductase from a Methane-Producing Archaeon

open access: yesAntioxidants, 2018
The redox regulation of proteins via reversible dithiol/disulfide exchange reactions involves the thioredoxin system, which is composed of a reductant, a thioredoxin reductase (TR), and thioredoxin (Trx).
