Abstract Epistructural tension is the reversible work per unit area required to span the aqueous interface of a soluble protein structure. The parameter accounts for the free-energy cost of imperfect hydration, involving water molecules with a shortage of hydrogen-bonding partnerships relative to bulk levels. The binding hot spots along protein-protein interfaces are identified with residues that contribute significantly to the epistructural tension in the free subunits. Upon association, such residues either displace or become deprived of low-coordination vicinal water molecules.
