Repeat proteins as versatile scaffolds for arrays of redox-active FeS clusters

Arrays of one, two and four electron-transfer active [4Fe-4S] clusters were constructed on modular tetratricopeptide repeat protein scaffolds, with the number of clusters determined solely by the size of the scaffold. The constructs show reversible redox activity and transient charge stabilization n...

Description
Summary:Arrays of one, two and four electron-transfer active [4Fe-4S] clusters were constructed on modular tetratricopeptide repeat protein scaffolds, with the number of clusters determined solely by the size of the scaffold. The constructs show reversible redox activity and transient charge stabilization necessary to facilitate charge transfer.
