Surface charges play a key role in determining the structure and function of proteins, DNA and larger biomolecular structures. For example, negatively charged DNA strands electrostatically interact with histone proteins, transcription factors, or polymerases thereby influencing the read-out of genetic information and the development of cancer. Similarly, the central process of protein folding and protein interaction, often governed by charges, is the major factor in protein-folding diseases such as Alzheimer's or Parkinson's Disease.
