A divalent cation-dependent variant of the glmS ribozyme with stringent Ca(2+) selectivity co-opts a preexisting nonspecific metal ion-binding site

Ribozymes use divalent cations for structural stabilization, as catalytic cofactors, or both. Because of the prominent role of Ca(2+) in intracellular signaling, engineered ribozymes with stringent Ca(2+) selectivity would be important in biotechnology. The wild-type glmS ribozyme (glmS(WT)) require...
