To unravel the molecular drivers of promiscuous anion recognition, we have employed a comprehensive approach - spanning experiment and theory - with the Staphylococcus carnosus nitrate regulatory element A (ScNreA) as a model. Thermodynamic analysis reveals that ScNreA complexation with native nitrate and nitrite or non-native iodide is an exothermic process. Further deconvolution of the association and dissociation kinetics for each anion reveals that the release event can be limiting, in turn, giving rise to the observed selectivity: nitrate > iodide > nitrite. These conclusions are supplemented with molecular dynamics simulations that capture an entry and exit pathway coupled to subtle global protein motions unique to each anion.

This study demonstrates an enhancement in the temperature sensitivity of Tb(III) emission by introducing an energy escape pathway from the ligand triplet state. A dinuclear Tb(III)-Nd(III) complex containing hexafluoroacetylacetonate (hfa) and triphenylene bridging ligands was prepared, which exhibits temperature-dependent energy transfer from the Tb(III)-emitting state to the hfa triplet state. The triplet level of the hfa ligand is similar to that of the triphenylene ligand, inducing effective energy transfer from hfa to Nd(III) via the triphenylene ligands.
