Dynamic coordination of two-metal-ions orchestrates λ-exonuclease catalysis
Metal ions at the active site of an enzyme act as cofactors, and their dynamic fluctuations can potentially influence enzyme activity. Here, we use λ-exonuclease as a model enzyme with two Mg(2+) binding sites and probe activity at various concentrations of magnesium by single-molecule-FRET. We find...
