Despite decades of effort, it remains challenging, if not impossible, to achieve similar transport performance similar to natural channels. Inspired by the known crystal structures of transmembrane channel proteins, protein sequence-structure-transport relationships have been applied to guide material design. However, producing both molecularly defined channel sizes and channel lumen surfaces that are chemically diverse and spatially heterogeneous have been out of reach. We show that a 4-monomer-based random heteropolymer (RHP) exhibits selective proton transport at a rate similar to those of natural proton channels. Statistical control over the monomer distribution in the RHP leads to well-modulated segmental heterogeneity in hydrophobicity, which facilitates the single RHP chains to insert into lipid bilayers. This in turn produces rapid and selective proton transport, despite the sequence variability among RHP chains. We have demonstrated the importance of:the adaptability enabled by the statistical similaritythe modularity afforded by monomer chemical diversity to achieve uniform behavior in heterogeneous systems. 

Protein-based materials have the potential to change the current paradigm of materials science. However, it still remains a challenge to preserve protein hierarchical structure and function while making them readily processable. Protein structure is inherently fluid, and it is this property that contributes to their fragility outside of their native environment. Through the use of rationally designed statistically random heteropolymers, it is possible to stabilize proteins at each hierarchical level and process them in organic solvents, a common need for materials fabrication. The chemical and architectural complexities of statistically random heteropolymers provide a modular platform for tunable protein-polymer-solvent interactions. This provides opportunities not offered by small molecule surfactants or amphiphilic block copolymers. Through evaluation of horseradish peroxidase and green fluorescent protein structure, we show that statistically random heteropolymers can stabilize enzymes. Allowing for activity retention when stored in organic solvent, over 80% activity was observed after 24 hours. Furthermore, horseradish peroxidase and chymotrypsin proteins, when encapsulated in statistically random heteropolymers, are still accessible to their substrates while remaining inaccessible to the denaturing organic solvent. Statistically random heteropolymers have potential in creating stimuli-reponsive materials and nanoreactors composed of proteins and synthetic materials.
