Query: Dipole-dipole interactions in protein-protein complexes: a quantum
  mechanical study of the ubiquitin-Dsk2 complex   Quantum mechanical calculations are performed on the proteins that constitute
the ubiquitin-Dsk2 complex whose atomic structure has been experimentally
determined by NMR spectroscopy (PDB id 1WR1). The results indicate that the
dipole moment vectors of the two proteins are aligned in a head-to-tail
orientation while forming and angle of ~130{\deg}. Hence, attractive
dipole-dipole interactions not only stabilize the protein-protein complex but
they are likely to favor the correct orientation of the proteins during the
formation of the complex.
