Seltene Erden in Proteinen: von Biorecycling bis zu Designer-Enzymen

Due to their distinct magnetic and optical properties, lanthanides are an essential resource for many modern technologies. The increasing knowledge on lanthanide-utilizing bacteria, and the proteins they evolved to specifically bind these metals, fosters new strategies towards bio-inspired lanthanide recycling and separation. Furthermore, de novo designed proteins have been equipped with lanthanide binding sites to develop functional tools such as MRI contrast agents or artificial photoenzymes.
