Answer:
Due to hydrophilic nature of E amino acid, it will make it self to be exposed on protein surface and will disrupt the structure and potentially the function of troponin. 
Explanation:
Since the E amino acid is hydrophilic, it will try to be exposed on the surface of the protein and thus will disrupt the tertiary structure and potentially the function of troponin.
