REVERSIBLE ENZYMATIC SYNTHESIS OF FLAVIN-ADENINE DINUCLEOTIDE

Journal of Biological Chemistry, 1950
An enzyme has been partially purified from brewer's yeast which catalyzes the reversible reaction between riboflavin phosphate and adenosine triphosphate (ATP) on the one hand and flavin-adenine dinucleotide (FAD) and inorganic pyrophosphate on the other in the presence of magnesium ions.

Circulating Amino Acid Network Remodeling Reveals Systemic Metabolic Reprogramming Predictive of Colorectal Cancer Recurrence and Metastasis

Advanced Science, EarlyView.
Blood‐based amino acid patterns measured by 19F NMR reveal hidden metabolic changes in colorectal cancer. By analyzing how these amino acids interact as a network, machine learning models identify patients at higher risk of recurrence and metastasis.

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

Advanced 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.

Flavin Electron Shuttles Dominate Extracellular Electron Transfer by Shewanella oneidensis

mBio, 2013
Shewanella oneidensis strain MR-1 is widely studied for its ability to respire a diverse array of soluble and insoluble electron acceptors. The ability to breathe insoluble substrates is defined as extracellular electron transfer and can occur via direct
