Chimeragenesis of distantly-related proteins by noncontiguous recombination.
We introduce a method for identifying elements of a protein structure that can be shuffled to make chimeric proteins from two or more homologous parents. Formulating recombination as a graph-partitioning problem allows us to identify noncontiguous segments of the sequence that should be inherited together in the progeny proteins. We demonstrate this noncontiguous recombination approach by const...
متن کاملGeneral method for sequence-independent site-directed chimeragenesis.
We have developed a simple and general method that allows for the facile recombination of distantly related (or unrelated) proteins at multiple discrete sites. To evaluate the sequence-independent site-directed chimeragenesis (SISDC) method, we have recombined beta-lactamases TEM-1 and PSE-4 at seven sites, examined the quality of the chimeric genes created, and screened the library of 2(8) (25...
متن کاملRecombination and chimeragenesis by in vitro heteroduplex formation and in vivo repair.
We describe a simple method for creating libraries of chimeric DNA sequences derived from homologous parental sequences. A heteroduplex formed in vitro is used to transform bacterial cells where repair of regions of non-identity in the heteroduplex creates a library of new, recombined sequences composed of elements from each parent. Heteroduplex recombination provides a convenient addition to e...

Directed evolution has become a powerful tool for developing enzyme and whole cell based biocatalysts. Significant recent advances include the creation of novel enzyme functions and the development of several new efficient directed evolution methods. The combination of directed evolution and rational design promises to accelerate the development of biocatalysts for applications in the pharmaceu...

Laboratory evolutionists continue to generate better enzymes for industrial and research applications. Exciting developments include new biocatalysts for enantioselective carbon–carbon bond formation and fatty acid production in plants. Creative contributions to the repertoire of evolutionary methods will ensure further growth in applications and expand the scope and complexity of biological de...
