Metals/Ions

EC Number Metals/Ions Comment Organism Structure
1.14.11.17 Fe2+ fully reversible redox-linked conformational changes in three forms of TauD. The hysteresis between the oxidation and reduction Nernstian NPSV profiles arises primarily from isomerization between two separate ferric/ferrous redox couples of the protein Escherichia coli
