  • Metalloenzymes play essential roles in biology but controlling outer-sphere interactions to influence their functions remains a significant challenge. Here, the authors demonstrate how variations in the primary, secondary, and outer coordination-sphere interactions of de novo designed artificial copper proteins influence their catalytic and electron transfer properties.

  • Despite decades of research into heme-copper oxidases, the advantages provided by copper over iron as the non-heme metal has remained unclear. Now, the preference of copper over iron has finally been explained. Copper favours faster electron transfer and higher O–O bond activation, which results in much higher oxidase activity than would be achieved by an iron equivalent.
