The Thermodynamics of Xanthine Oxidoreductase Catalysis [PDF]
Antioxidants & Redox Signaling, 1999 Xanthine oxidoreductase is a complex enzyme found in a wide range of organisms. Recent interest in this enzyme stems from its ability to produce reactive oxygen species under a range of conditions. It is found as a homodimer, each unit containing a molybdopterin cofactor, two iron sulfur centers, and FAD.

Advanced Functional Materials, EarlyView.Lanthanide ytterbium ions are introduced into Bi2WO6 nanosheets to boost ROS generation under US stimulation. These ytterbium‐doped Bi2WO6 nanosheets serve as efficient sonosensitizers, enabling broad‐spectrum bacterial eradication. To improve biocompatibility for in vivo sonodynamic therapy, the sonosensitizers are integrated into hydrogel matrix ...

Oxidoreductases and metal cofactors in the functioning of the earth
Essays in Biochemistry, 2023 Abstract Life sustains itself using energy generated by thermodynamic disequilibria, commonly existing as redox disequilibria. Metals are significant players in controlling redox reactions, as they are essential components of the engine that life uses to tap into the thermodynamic disequilibria necessary for metabolism.
