Abstract

Previously, we reported that the substrate shape recognition of the Escherichia coli ribonuclease (RNase) P ribozyme depends on the concentration of magnesium ion in vitro. We additionally examined the Bacillus subtilis RNase P ribozyme and found that the B. subtilis enzyme also required high magnesium ion, above 10 mM, for cleavage of a hairpin substrate. The results of kinetic studies showed that the metal ion concentration affected both the catalysis and the affinity of the ribozymes toward a hairpin RNA substrate.
