List of protein pairs utilized in the work. Boldfaced PDB codes indicate extreme halophiles.

a) Protein Data Bank code

b) Number of monomers in the biological unit

c) Source organisms. (A) = Archaea; (B) = Bacteria

d) Optimal range of NaCl concentration for growth. The first 9 lines contain structures from extreme halophiles; the remaining 6 lines report moderate halophiles.

e) The survival strategy adopted by corresponding organism: "salt-in" or "osmolytes" strategy

f) Crystallographic resolution

g) Protein name as reported in the Protein Data Bank

h) Sequence percentage of identity between protein pairs
