Protein Self-Assembly

Chemical Design of Protein Self-Assembly

Whether through the formation of complex biological machines or architectures with advanced materials properties, protein self-assembly is the predominant means of building complexity in living systems. The formation of natural protein assemblies typically involves numerous weak, non-covalent interactions, which are difficult to design from scratch. Thus, a major thrust in our lab has been to simplify the protein design space by the use of rationally designed metal coordination interactions and dynamic covalent bonds, often in conjunction with computational design. These approaches have yielded both discrete and infinite/periodic assemblies which exhibit dynamic behavior and novel mechanical attributes. Currently, we are seeking to expand our toolbox of chemical bonding strategies and building blocks to construct protein assemblies with structural, functional and mechanical properties beyond those explored by natural evolution.
