The self-assembly of proteins into higher-order superstructures is ubiquitous in biological systems. Genetic methods comprising both computational and rational design strategies are emerging as powerful methods for the design of synthetic protein complexes with high accuracy and fidelity. Although useful, most of the reported protein complexes lack a dynamic behavior, which may limit their potential applications. On the contrary, protein engineering by using chemical strategies offers excellent possibilities for the design of protein complexes with stimuli-responsive functions and adaptive behavior. However, designs based on chemical strategies are not accurate and therefore, yield polydisperse samples that are difficult to characterize. Here, we describe simple design principles for the construction of protein complexes through a supramolecular chemical strategy. A micelle-assisted activity-based protein-labeling technology has been developed to synthesize libraries of facially amphiphilic synthetic proteins, which self-assemble to form protein complexes through hydrophobic interaction. The proposed methodology is amenable for the synthesis of protein complex libraries with molecular weights and dimensions comparable to naturally occurring protein cages. The designed protein complexes display a rich structural diversity, oligomeric states, sizes, and surface charges that can be engineered through the macromolecular design. The broad utility of this method is demonstrated by the design of most sophisticated stimuli-responsive systems that can be programmed to assemble/disassemble in a reversible/irreversible fashion by using the pH or light as trigger.

Effects of polymer architecture and nanoenvironment in acylation reactions employing dendritic (Dialkylamino)pyridine catalysts

The role of architecture and nanoenvironment in the catalytic properties of dendritic polymers containing 4-(dialkylamino)pyridines was investigated in the context of acylation reactions employing sterically demanding tertiary alcohols as substrates. Frechet-type benzyl ether and aliphatic ester dendrimers were prepared in a convergent manner from a common trivalent core containing three DMAP groups while a linear polymer was dendronized with aliphatic esters using a divergent growth scheme. Catalysis experiments clearly indicate that nanoenvironment plays the dominant role in determining the activity of the polymer catalysts, with the polyester platform being superior to the benzyl ether. Polymer architecture played little or no role in affecting catalysis. With respect to molecular transport and catalysis, this represents the first comparative study of the effect of architecture and nanoenvironment using structurally similar dendritic materials.
