Identify the coiled-coil motif by RDC-based molecular replacement analysis. 3) Define the subtle curvature and super-coiling of the constituent helices by RDC refinement 4) Assemble parallel and anti-parallel models of the coiled-coil dimer using knowledge-based inter-molecular distance restraints. 5) Derive the correct monomer-monomer orientation by comparing experimental RDCs with those predicted from the 3D charge distribution and shape of the alternative structural models.
