What’s the difference between biochemistry and chemical biology, you might ask? Well, it’s all about perspective and how you approach the science. Join us to hear how a chemical biologist approaches biosynthesis of natural products.
We’re joined in this episode by Dr. Sarah Barry, Reader in Chemical Biology at King’s College London. Sarah started with an interest in biochemistry, went into organic chemistry because it was more concrete, and now applies her chemist’s approach to understanding and manipulating biosynthesis of natural products for important areas of research, including antibiotics.
This insightful conversation gives a peek into the mind of a chemical biologist’s way of thinking about and approaching challenges that span biology and chemistry. We learn about the historical challenges of discovering and synthesizing natural products, but we then hear about how innovations in molecular biology are allowing researchers to revisit this field with a new approach. Sarah and her team identify and manipulate genes, express and purify proteins in the lab, and then characterize those enzymes for their abilities to drive biocatalytic transformations that are beyond challenging using traditional organic or inorganic chemistry approaches. Our conversation spans from the details of the molecular biology methods used, to the high-level applications being explored in this research, all with an ease that only someone this interdisciplinary could do.
