CHIMERIC ZINC FINGER RECOMBINASES OPTIMIZED FOR CATALYSIS BY DIRECTED EVOLUTION

摘要

The present invention is directed to chimeric recombinases comprising a serine recombinase operatively linked to a zinc finger nucleotide binding domain such that the chimeric recombinase protein catalyzes site-specific recombination at a DNA site specifically bound by the zinc finger nucleotide binding domain. The serine recombinase can be one of several naturally occurring serine recombinases. The invention also includes nucleic acids encoding the chimeric recombinases, vectors including the nucleic acids, host cells transformed or transfected with the vectors, methods of using the chimeric recombinases to carry out recombination, methods of using substrate-linked protein evolution to generate additional chimeric recombinases, methods of using the chimeric recombinases for gene therapy, and pharmaceutical compositions.
