Atomic packing at a specific and a nonspecific interface. The pink balls represent atoms at the interface of (a) one subunit of the κ-bungarotoxin dimer (PDB code 1kba
) and (b) the pokeweed protein crystal dimer (PDB code 1qci
). Each interface buries approximately 1000 Å2 and includes about 50 atoms, but whereas these atoms form a compact patch in the case of the homodimer, they spread apart in the crystal contact. |
