A peptide hydrogel derived from a fragment of human cardiac troponin C

Chem Commun (Camb). 2016 Mar 14;52(21):4056-9. doi: 10.1039/c6cc00209a.


The human cardiac troponin C peptide fragment H-V(9)EQLTEEQKNEFKAAFDIFVLGA(31)-OH, which covers helix-A in the native protein, self-assembles into β-sheet fibrils in solution. These fibrils further entangle to give a hydrogel. This peptide may therefore serve as a template for development of novel biomaterials.
