Talk Title: “Conformational control: from single molecules to biotechnologies”
Abstract: It has been known over forty years that proteins have multiple conformations. How these conformations are related to function and how to exploit our understanding of conformational control to create novel behaviors and biotechnologies is an active area of research. I will illustrate two examples, CRISPR Cas9 and helicases, where biophysical understanding of regulatory mechanisms led to the creation of new biotechnologies through chemically or light-induced conformational control.
