Enhanced rare-earth separation with a metal-sensitive lanmodulin dimer

Abstract
Abstract Technologically critical rare-earth elements are notoriously difficult to separate, owing to their subtle differences in ionic radius and coordination number 1–3 . The natural lanthanide-binding protein lanmodulin (LanM) 4,5 is a sustainable alternative to conventional solvent-extraction-based separation 6 . Here we characterize a new LanM, from Hansschlegelia quercus ( Hans -LanM), with an oligomeric state sensitive to rare-earth ionic radius, the lanthanum(III)-induced dimer being >100-fold tighter than the dysprosium(III)-induced dimer. X-ray crystal structures illustrate how picometre-scale differences in radius between lanthanum(III) and dysprosium(III) are propagated to Hans -LanM’s…
