METHODS OF GENERATING MODIFIED POLYNUCLEOTIDE LIBRARIES AND METHODS OF USING THE SAME FOR DIRECTED PROTEIN EVOLUTION

摘要

The invention provides for methods of generating modified polynucleotide libraries by inserting and/or deleting at least three nucleotide residues in polynucleotide sequences. Theses methods may be used with other methods of gene modification such as gene shuffling. The invention further provides methods of directed molecular evolution using the modified polynucleotide libraries produced by these methods.
