  • To discuss the influence of water on protein-DNA and protein-RNA interfaces.

Main Methods:

  • Literature review of experimental and computational studies.
  • Analysis of existing data on hydration and macromolecular structure.
  • Synthesis of findings related to water's role in biological systems.

Main Results:

  • Water is essential for achieving and maintaining native protein structures.
  • Fluctuations in water-mediated hydrogen bonds drive protein flexibility and conformational changes.
  • Water significantly impacts DNA and RNA structure and interactions.

Conclusions:

  • Water is a fundamental component in the structural biology of proteins and nucleic acids.
  • Understanding water's dynamic role is key to deciphering complex biological processes.
  • Further research is needed to address open questions regarding water's precise mechanisms.
