Laboratory-directed protein evolution.
Systematic approaches to directed evolution of proteins have been documented since the 1970s. The ability to recruit new protein functions arises from the considerable substrate ambiguity of many proteins. The substrate ambiguity of a protein can be interpreted as the evolutionary potential that allows a protein to acquire new specificities through mutation or to regain function via mutations t...
متن کاملDesign by Directed Evolution
The stunning array of features and functions exhibited by proteins in nature should convince most scientists of the power of evolutionary design processes. Natural selection acting on populations over long periods of time has generated a vast number of proteins ideally suited to their biological functions. When we try to recruit these remarkable molecular machines for new taskssfrom serving as ...
متن کاملDesign of protein function leaps by directed domain interface evolution.
Most natural proteins performing sophisticated tasks contain multiple domains where an active site is located at the domain interface. Comparative structural analyses suggest that major leaps in protein function occur through gene recombination events that connect two or more protein domains to generate a new active site, frequently occurring at the newly created domain interface. However, such...
متن کاملOptimizing the search algorithm for protein engineering by directed evolution.
An in silico protein model based on the Kauffman NK-landscape, where N is the number of variable positions in a protein and K is the degree of coupling between variable positions, was used to compare alternative search strategies for directed evolution. A simple genetic algorithm (GA) was used to model the performance of a standard DNA shuffling protocol. The search effectiveness of the GA was ...
متن کاملBiocatalyst development by directed evolution.
Biocatalysis has emerged as a great addition to traditional chemical processes for production of bulk chemicals and pharmaceuticals. To overcome the limitations of naturally occurring enzymes, directed evolution has become the most important tool for improving critical traits of biocatalysts such as thermostability, activity, selectivity, and tolerance towards organic solvents for industrial ap...
