SOCKET, Woolfson Group, University of Bristol
The SOCKET program finds the Knobs-into-Holes mode of packing between alpha-helices (Crick, 1953) which is characteristic of coiled coils. It unambiguously defines the beginning and end of coiled-coil motifs in protein structures and assigns a heptad register to the sequence, highlighting the core-residues with a RasMol script (Sayle & Milner-White, 1995) if required.
