Supramolecular structures arising from a broad range of chemical archetypes are of great technological promise. Defining such structures at the nanoscale is crucial to access principally new types of functional materials for applications in bionanotechnology. In this vein, biomolecular self-assembly has emerged as an efficient approach for building synthetic nanostructures from the bottom up. The approach predominantly employs the spontaneous folding of biopolymers to monodisperse three-dimensional shapes that assemble into hierarchically defined mesoscale composites. An immediate interest here is the extraction of reliable rules that link the chemistry of biopolymers to the mechanisms of their assembly. Once established these can be further harnessed in designing supramolecular objects de novo. Different biopolymer classes compile a rich repertoire of assembly motifs to facilitate the synthesis of otherwise inaccessible nanostructures. Among those are peptide α-helices, ubiquitous folding elements of natural protein assemblies. These are particularly appealing candidates for prescriptive supramolecular engineering, as their well-established and conservative design rules give unmatched predictability and rationale. Recent developments of self-assembling systems based on helical peptides, including fibrous systems, nanoscale linkers and reactors will be highlighted herein.

Self-assembling peptides are attracting wide interest as biodegradable building blocks to achieve functional nanomaterials that do not persist in the environment. Amongst the many applications, biocatalysis is gaining momentum, although a clear structure-to-activity relationship is still lacking. This work applied emerging design rules to the heterochiral octapeptide sequence His–Leu–DLeu–Ile–His–Leu–DLeu–Ile for self-assembly into nanofibrils that, at higher concentration, give rise to a supramolecular hydrogel for the mimicry of esterase-like activity. The peptide was synthesized by solid-phase and purified by HPLC, while its identity was confirmed by 1H-NMR and electrospray ionization (ESI)-MS. The hydrogel formed by this peptide was studied with oscillatory rheometry, and the supramolecular behavior of the peptide was investigated with transmission electron microscopy (TEM) analysis, circular dichroism (CD) spectroscopy, thioflavin T amyloid fluorescence assay, and attenuated total reflectance (ATR) Fourier-transform infrared (FT-IR) spectroscopy. The biocatalytic activity was studied by monitoring the hydrolysis of p-nitrophenyl acetate (pNPA) at neutral pH, and the reaction kinetics followed an apparent Michaelis–Menten model, for which a Lineweaver–Burk plot was produced to determine its enzymatic parameters for a comparison with the literature. Finally, LC–MS analysis was conducted on a series of experiments to evaluate the extent of, if any, undesired peptide acetylation at the N-terminus. In conclusion, we provide new insights that allow gaining a clearer picture of self-assembling peptide design rules for biocatalysis.
