A method for DNA reassembly after random fragmentation, and its application to mutagenesis of nucleic acid sequences by in vitro or in vivo recombination is described. In particular, a method for the production of nucleic acid fragments or polynucleotides encoding mutant proteins is described. The present invention also relates to a method of repeated cycles of mutagenesis, shuffling and selection which allow for the directed molecular evolution in vitro or in vivo of proteins.
[ What is claimed is:] [1.] A method for evolving a green fluorescent protein (GFP) protein and a polynucleotide encoding same, comprising(1) providing a population of DNA segments encoding GFP at least one of which is in cell-free form;(2) shuffling the population of DNA segments encoding GFP where
[ What is claimed is:] [1.] A method for evolving a green fluorescent protein (GFP) protein and a polynucleotide encoding same, comprising(1) providing a population of DNA segments encoding GFP at least one of which is in cell-free form;(2) shuffling the population of DNA segments encoding GFP whereby the segments recombine to form recombinant segments,(3) selecting or screening for recombinant segments having evolved toward a desired property;repeating (2) and (3) with the recombinant segments in (3) providing the population of DNA segments in (1) at each cycle of repetition until a recombinant segment has acquired the desired property.
