Lewis acid catalysis of phosphoryl transfer from a copper(II)-NTP complex in a kinase ribozyme
The chemical strategies used by ribozymes to enhance reaction rates are revealed in part from their metal ion and pH requirements. We find that kinase ribozyme K28(1-77)C, in contrast with previously characterized kinase ribozymes, requires Cu(2+) for optimal catalysis of thiophosphoryl transfer fro...
