Surveying current state-of-the-art techniques, this book provides a comprehensive overview of this exciting field. The book focusses on modern techniques that generate better performing enzymatic systems and novel biosynthetic routes to (non-)natural products. This includes the use of molecular techniques in protein design and engineering, the construction of artificial metabolic pathways and the application of computational methods for enzyme discovery and design. The book provides researchers with a greater understanding of current and emerging trends in biocatalysis.
