The aim of this module is to provide students with a knowledge and understanding of the application of enzymes in organic synthesis with a focus on selectivity and sustainability. Selected industrial examples will illustrate where biocatalysis can replace or be combined with conventional chemical reactions in drug synthesis. The module will include an introduction to molecular biology, exciting new developments in the field such as directed evolution for the creation of designer enzymes, creation of artificial enzymes by combining chemo-and biocatalysis and development of synthetic pathways using enzymes. Industrial biotechnology is an important area for a sustainable future and this module will provide a solid foundation from a chemistry perspective.
