Evolving new molecular function
First Claim
1. An in vitro method of enriching a product of a nucleic acid-templated synthesis, the method comprising the steps of:
- (a) providing a first library of molecules comprising a plurality of reaction products of a nucleic acid templated synthesis, which are not nucleic acids, wherein each reaction product is covalently attached to a corresponding oligonucleotide that templated the synthesis of the reaction product, and wherein each oligonucleotide comprises a nucleotide sequence indicative of the reaction product associated therewith, and wherein a portion of said reaction products are capable of binding to a preselected binding moiety;
(b) exposing said first library of molecules to said binding moiety under conditions to permit reaction product capable of binding said binding moiety to bind thereto, wherein the reaction product has a Kd for the binding moiety of no less than 0.9 nM;
(c) removing unbound reaction products; and
(d) eluting bound reaction product from said binding moiety to produce a second library of molecules enriched at least 50-fold for reaction product that binds said binding moiety relative to said first library.

Abstract
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.

19. An in vitro method of enriching a product of a nucleic acid-templated synthesis, the method comprising the steps of:
-
(a) providing a first library of molecules comprising a plurality of reaction products of a nucleic acid templated synthesis, which are not nucleic acids, wherein each reaction product is covalently attached to a corresponding oligonucleotide that templated the synthesis of the reaction product, wherein each oligonucleotide comprises a nucleotide sequence indicative of the reaction product associated therewith, wherein no oligonucleotide is linked by a direct or indirect covalent or non-covalent interaction to a capturable moiety selected from the group consisting of biotin, avidin and streptavidin; and
wherein a portion of said reaction products are capable of binding to a preselected binding moiety;(b) exposing said first library of molecules to said binding moiety under conditions to permit reaction product capable of binding said binding moiety to bind thereto; (c) removing unbound reaction products; and (d) eluting bound reaction product from said binding moiety to produce a second library of molecules enriched at least 50-fold for reaction product that binds said binding moiety relative to said first library.
