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

The human cardiac troponin C peptide fragment H-V9EQLTEEQKN EFKAAFDIFVLGA31-OH, which covers helix-A in the native protein, self-assembles into b-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.
