De novo Design of Small Molecule Binding and Sensing Proteins
Taylor Auditorium, Frick Chemistry Lab B02
Host: BioEngineering/Chemistry
A general computational method to build small molecule-protein interfaces from scratch
would be widely useful for many challenges, including ligand binder, sensor design, and
enzyme engineering. Yet, designing proteins to bind small molecules is extremely challenging
because the problem requires a highly accurate sampling in a gigantic sampling space. In
this talk, I will go through how we approach the small molecule binding problem through
building machine learning-based protein design methods and successfully demonstrating
their robustness through designing binders to various ligands, including polar and flexible
ones. Using the designed binders, I further developed a general method to turn binders into
sensors through building chemically induced oligomerization systems. I will also project how
our methods can revolutionize enzyme engineering by significantly increasing our screening
capability and enabling large structural manipulations that were impossible before on enzyme
redesign.
