Examples of interactions mediated by electrostatic forces. (a) Intramolecular salt bridges are involved in protein folding and stability; (b) Cotranslational interaction with ribosomes may influence secondary structure formation; (c) Long-range interaction between charged residues is involved in tertiary structure acquisition; (d) Surface charge can act as a direct proteasome signal and trigger protein degradation ; (e) Electrostatic can facilitate complex formation; (f) Conformational exchange; (g) Positive charge is required for rycin binding to rRNA (h) Protein binding to DNA could hamper binding of other molecules modulating DNA accessibility
