Crystallographic study of Ln(III)-PTE-R18. (a) Structure of the Eu-PTE-R18 active site from data collected at 9.5 keV (PDB entry 8uqy) with the anomalous map at 5σ (cyan) and 10σ (magenta). (b) Fluorescence emission of the Eu-PTE-R18 crystal. (c) Structure of the Gd-PTE-R18 active site from data collected at 9.5 keV (PDB entry 8uqz) with the anomalous map at 4σ (cyan) and 20σ (magenta). (d) Fluorescence emission of the Gd-PTE-R18 crystal. |
