β¦ Synopsis
In the past year, a number of oxidative enzymes have been the target of directed evolution. Catalase reaction specificity has been shifted to peroxidase, the high pH, thermal and oxidative stability of a fungal peroxidase has been dramatically improved, and the substrate specificity of cytochrome P450 has been altered to include substrates that the wild-type enzymes are incapable of oxidizing.

## Abstract Directed evolution has become the preferred engineering approach to generate tailorβmade enzymes. The method follows the design guidelines of nature: Darwinian selection of genetic variants. This review discusses the different stages of directed evolution experiments with the focus on d
