Title: Modular Self-Assembly of Protein Cage Lattices for Multistep Catalysis

Journal Article · · ACS Nano

The assembly of individual molecules into hierarchical structures is a promising strategy for developing novel three-dimensional materials with potential for collective behavior and properties beyond those of the individual building blocks. Virus-like particles (VLPs), inspired by the elegant assembly of virus capsids, are examples of hierarchically assembled nanoparticles constituted from a limited number of protein subunits. Here we demonstrate the construction of bulk materials with two levels of hierarchy; the formation of catalytically active VLPs through directed enzyme encapsulation into VLPs, and self-assembly of these VLP building blocks into ordered three-dimensional lattices. The resulting materials, obtained by rational design of the exterior surface of the VLP to modulate interparticle interactions, adopt a face-centered cubic lattice that is independent of the enzyme cargo within the interior. We describe the design, characterization, and implications of a hierarchical structure composed of two enzyme packaged VLPs that are catalytically coupled to synthesize isobutanol.
