The New World of ribozymes.
The number of RNA molecules that have novel catalytic activities has dramatically increased during the past two years. This ribozymic boom is not due to the discovery of additional examples of natural ribozymes but rather to the development of artificial ribozymes isolated by in vitro selection and evolution techniques. The structural and functional complexities of these artificial ribozymes, however, do not match those of the larger natural ribozymes. The understanding of both RNA structure and catalysis performed by natural and artificial ribozymes paves the way for the creation of RNA molecules that are able to efficiently catalyze more complex reactions.
