Protonation/deprotonation-driven switch for the redox stability of low-potential [4Fe-4S] ferredoxin
Ferredoxin is known as a simple iron-sulfur (Fe-S) protein, and is ubiquitous in plants, animals, and prokaryotes(1, 2). Ferredoxins function as electron carriers for fundamental metabolic processes such as gluconeogenesis/glycolysis, photosynthesis, …
