Single-component peptide coacervates mimicking mussel foot protein-3S were adapted for rapid pressure-sensitive wet adhesion. The coacervate upon compression exhibited orders of magnitude higher underwater adhesion at 2 N m−1 than thin films of the most adhesive mussel-foot-derived peptides reported to date.

ABSTRACTIn this study, a molecular self-assembly strategy to develop a novel protein scaffold for amplifying the extent and variety of proteins displayed on the surface ofSaccharomyces cerevisiaeis presented. The cellulosomal scaffolding protein cohesin and its upstream hydrophilic domain (HD) were genetically fused with the yeast Ure2p N-terminal fibrillogenic domain consisting of residues 1 to 80 (Ure2p1-80). The resulting Ure2p1-80-HD-cohesin fusion protein was successfully expressed inEscherichia colito produce self-assembled supramolecular nanofibrils that serve as a novel protein scaffold displaying multiple copies of functional cohesin domains. The amyloid-like property of the nanofibrils was confirmed via thioflavin T staining and atomic force microscopy. These cohesin nanofibrils attached themselves, via a green fluorescent protein (GFP)-dockerin fusion protein, to the cell surface ofS. cerevisiaeengineered to display a GFP-nanobody. The excess cohesin units on the nanofibrils provide ample sites for binding to dockerin fusion proteins, as exemplified using an mCherry-dockerin fusion protein as well as theClostridium cellulolyticumCelA endoglucanase. More than a 24-fold increase in mCherry fluorescence and an 8-fold increase in CelA activity were noted when the cohesin nanofibril scaffold-mediated yeast display was used, compared to using yeast display with GFP-cohesin that contains only a single copy of cohesin. Self-assembled supramolecular cohesin nanofibrils created by fusion with the yeast Ure2p fibrillogenic domain provide a versatile protein scaffold that expands the utility of yeast cell surface display.

Inspired from the one-component self-coacervation of tropoelastin and mussel foot protein-3s, we created the first non-ionic, single component coacervates that can coacervate in a all ranges of pH (acidic to basic) and wide range of ionic strengths with degradability, rapid curing and strong underwater adhesion. In contrast to the complex coacervates, these ‘charge-free’ coacervates are potential candidates as tissue adhesives and sealants, adhesives for sensor attachment to wet skin, and as sprayable adhesives. Their potential use in the clinic arises from their enhanced stability to changes in external conditions, cytocompatibility, biodegradability and modular nature in incorporating various functional groups and crosslinkers.
