a Association energies in this and other tables were calculated only for the buried area of the dimer and do not include the rotation and translation components (Horton and Lewis 1992) derived from the loss of rotation and translational freedom of one of the monomers.
b Buried area at the interface between two monomers.
c Resolution of the crystal structure in Ångstrom.
