    摘要: The present invention provides in vivo systems in which activity of a biological cleavage enzyme, such as a site-specific recombinase, a homing endonuclease, or an intein, is linked to cell viability and therefore can be selected. The invention further provides methods of making cells in which the activity of a biological cleavage enzyme is linked to viability, as well as methods of identifying new biological cleavage enzymes, including enzymes having altered site specificity, using such cells.

    摘要: Nature evolves biological molecules such as proteins through iterated rounds of diversification, selection, and amplification. The power of Nature and the flexibility of organic synthesis are combined in nucleic acid-templated synthesis. The present invention provides a variety of template architectures for performing nucleic acid-templated synthesis, methods for increasing the selectivity of nucleic acid-templated reactions, methods for performing stereoselective nucleic acid-templated reactions, methods of selecting for reaction products resulting from nucleic acid-templated synthesis, and methods of identifying new chemical reactions based on nucleic acid-templated synthesis.
