Innovation by evolution: bringing new chemistry to life
NIH Director's Wednesday Afternoon Lecture Series Marshall W. Nirenberg Lecture Not satisfied with nature ’ s vast catalyst repertoire, we want to create new protein catalysts and expand the space of genetically encoded enzyme functions. I will describe how we can use the most powerful biological design process, evolution, to optimize existing enzymes and invent new ones, thereby circumventing our profound ignorance of how sequence encodes function. Using mechanistic understanding and mimicking nature ’ s evolutionary processes, we can generate whole new enzyme families that catalyze synthetically important rea...

Scalable platforms for generating RNA sensors and controllers
NIH Director's Wednesday Afternoon Lecture Series DeWitt Stetten, Jr. Lecture Biosensors are key components in engineered biological systems that interface with the large biochemical space in living cells and their environment. Aptamers, functional nucleic acid molecules that bind ligands, provide a powerful sensing element for many classes of molecules of interest. Although procedures such as SELEX have been quite successful in generating individual aptamers that bind proteins, generating small molecule aptamers has been more challenging due to the need to chemically modify the ligand to permit the recovery of binding seq...
