A two-metal ion mechanism operates in the hammerhead ribozyme-mediated cleavage of an RNA substrate
Evidence for a two-metal ion mechanism for cleavage of the HH16 hammerhead ribozyme is provided by monitoring the rate of cleavage of the RNA substrate as a function of La(3+) concentration in the presence of a constant concentration of Mg(2+). We show that a bell-shaped curve of cleavage activation...
