Elastin-like Polypeptide(GVGVP)(15)

Elastin-like polypeptides (ELPs) are protein polymers derived from human tropoelastin. One of their key features is that they exhibit phase separation that is often reversible whereby samples remain soluble below a transition temperature (Tt) but form coacervates above Tt. They have many possible applications for sensing, activation, and nano assembly. Furthermore, they are non-immunogenic, substrates for proteolytic biodegradation, and can be decorated with functional peptides, proteins, and small molecules. The general structure of polymeric ELPs is (GVGVP)(15）, where the monomeric unit is Gly-Val-Gly-Val-Pro. The NAU-CHINA 2023 team used this part in versatile model systems for biomaterials development. The polymerization between ELPs containing SpyTags and one containing SpyCatchers can proceed efficiently in a wine production environment.
