Study Notes
The text discusses protein engineering and the use of directed evolution to modify enzymes. It highlights the work of Prof. Frances Arnold in this field. The process involves creating a library of mutants using error-prone PCR or DNA shuffling, screening for the desired property, and isolating improved genes. The goal is to create enzymes with new properties, such as increased stability or catalytic activity. The text also discusses the importance of activation energy and provides an example of creating a novel enzyme from scratch using directed evolution methods.
