A general two-metal-ion mechanism for catalytic RNA.
A mechanism is proposed for the RNA-catalyzed reactions involved in RNA splicing and RNase P hydrolysis of precursor tRNA. The mechanism postulates that chemical catalysis is facilitated by two divalent metal ions 3.9 A apart, as in phosphoryl transfer reactions catalyzed by protein enzymes, such as...
