What is it about?
This study shows that changing just one amino acid at the N-terminus of short elastin-like peptides (Fn analogs) can drastically alter their ability to self-assemble with temperature. Aromatic or bulky residues promote stronger aggregation, while small or charged ones reduce it.

Why is it important?
Elastin-like peptides are promising building blocks for drug delivery and smart biomaterials, but controlling their phase behavior is challenging. This work demonstrates a simple way—single amino acid substitution—to fine-tune their temperature responsiveness. Such an approach makes it easier to design short, synthetically accessible peptides with customizable properties.
Perspectives
By identifying clear relationships between N-terminal residue type and peptide self-assembly, this research provides a practical guideline for molecular design. In the future, these customizable short peptides could be developed into versatile materials for medicine, biotechnology, and environmental applications.
