Abstract
A comparative study of water molecules and ion pairs in 11 Dps protein structures has been carried out. The invariant and common water molecules, the conserved residues interacting with them and the conserved ion pairs have been analyzed. Certain water molecules found on the interfaces between subunits are highly conserved and may be implicated in flexibility or continuing association of the subunits of the structure. It is possible that the water molecules, ion pairs and the special case of a water mediated charged network through a single water molecule are involved in maintaining the stability of the protein.
