What is it about?
This study investigates how the order of amino acids affects self-assembly of elastin-like peptides. Eleven shuffled variants of (FPGVG)₅ were synthesized, and most showed self-assembly, with some outperforming the original. Specific motifs, such as Pro-Gly, improved solubility and stability.

Why is it important?
Elastin-like peptides are promising building blocks for biomaterials, with applications ranging from drug delivery to tissue engineering. However, the molecular rules that govern their assembly are not fully understood. This work shows that the exact sequence of amino acids matters, and new motifs can be discovered that outperform natural ones. This opens the door to designing shorter, more efficient peptides that are easier to synthesize and tailor for specific biomedical and material applications.
Perspectives
Systematic sequence shuffling revealed new motifs that expand the design space of elastin-like peptides. This approach may enable custom peptides with predictable assembly and tunable properties for future biomedical and material applications.
