In the little more than a decade since the first reported applications of evolutionary design to enzyme enginee

Gaben von Nachiketas und Savitri annealing, and extension by a polymerase (..). Recombination occurs when fragments from different parents anneal at a region of high sequence identity. Following this reassembly reaction, PCR amplification with primers is used to generate full-length chimeras suitable for cloning into an expression vector.

Generating Mutant Libraries Using Error-Prone PCRolymerase (.,.). . polymerase (.) is commonly used because of its naturally high error rate, with errors biased toward AT to GC changes. However, recent protocols include the use of a newly-developed polymerase whose biases allow for increased variation in mutation type (i.e., more GC to AT changes) (..).

Evolution of Microorganisms Using Mutator Plasmids.). It is well documented that mutator strains can evolve rapidly to produce offsprings with novel phenotypes. However, their application for research or as industrial production hosts has been prevented by their very limited genetic stability.

Furthermore, ligation and transformation of the recombinant plasmids must be performed using materials and conditions that yield a sufficient number of transformants (∼10.–10.) for identifying variants exhibiting desired properties.
