Directed evolution comprises two distinct steps that are typically applied in an iterative fashion: (1) generating molecular diversity and (2) finding among the ensemble of mutant sequences those proteins that perform the desired fu- tion according to the specified criteria. In many ways, the second step is the most challenging. No matter how cleverly designed or diverse the starting library, without an effective screening strategy the ability to isolate useful clones is severely diminished. The best screens are (1) high throughput, to increase the likelihood that useful clones will be found; (2) sufficiently sen- tive (i. e. , good signal to noise) to allow the isolation of lower activity clones early in evolution; (3) sufficiently reproducible to allow one to find small improvements; (4) robust, which means that the signal afforded by active clones is not dependent on difficult-to-control environmental variables; and, most importantly, (5) sensitive to the desired function. Regarding this last point, almost anyone who has attempted a directed evolution experiment has learned firsthand the truth of the dictum “you get what you screen for. ” The protocols in Directed Enzyme Evolution describe a series of detailed p- cedures of proven utility for directed evolution purposes. The volume begins with several selection strategies for enzyme evolution and continues with assay methods that can be used to screen enzyme libraries. Genetic selections offer the advantage that functional proteins can be isolated from very large libraries s- ply by growing a population of cells under selective conditions.

This book focuses on some of the most significant advances in enzyme engineering that have been achieved through directed evolution and hybrid approaches. On the 25th anniversary of the discovery of directed evolution, this volume is a tribute to the pioneers of this thrilling research field, and at the same time provides a comprehensive overview of current research and the state of the art. Directed molecular evolution has become the most reliable and robust method to tailor enzymes, metabolic pathways or even whole microorganisms with improved traits. By mirroring the Darwinian algorithm of natural selection on a laboratory scale, new biomolecules of invaluable biotechnological interest can now be engineered in a manner that surpasses the boundaries of nature. The volume is divided into two sections, the first of which provides an update on recent successful cases of enzyme ensembles from different areas of the biotechnological spectrum, including tryptophan synthases, unspecific peroxygenases, phytases, therapeutic enzymes, stereoselective enzymes and CO2-fixing enzymes. This section also provides information on the directed evolution of whole cells. The second section of the book summarizes a variety of the most applicable methods for library creation, together with the future trends aimed at bringing together directed evolution and in silico/computational enzyme design and ancestral resurrection.

Directed Evolution Library Creation: Methods and Protocols, Second Edition presents user-friendly protocols for both proven strategies and cutting-edge approaches for the creation of mutant gene libraries for directed evolution. As well as experimental methods, information on current computational approaches is provided in a user-friendly format that will allow researchers to make informed choices without needing to comprehend the full technical details of each algorithm. Directed evolution has become a fundamental approach for engineering proteins to enhance activity and explore structure-function relationships, and has supported the rapid development of the field of synthetic biology over the last decade. Divided into three convenient sections, topics include point mutagenesis strategies, recombinatorial methods wherein genetic diversity is sourced from multiple parental genes that are combined via either homology-dependent or -independent techniques and a variety of computational methods to guide the design and analysis of mutant libraries. Written in the successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible protocols and notes on troubleshooting and avoiding known pitfalls. Authoritative and easily accessible, Directed Evolution Library Creation: Methods and Protocols, Second Edition will serve as a reliable manual for both novice and experienced protein engineers and synthetic biologists and will enable further technical innovation and the exploitation of directed evolution for a deeper understanding of protein design and function.
