Integrative structural determination of the protein complexes proceeds through four main stages: (1) data is first gathered from various structural elucidation methodologies; (2) subunits are represented from high-resolution structures while other forms of low-resolution structural data are translated into spatial restraints; (3) configurational sampling produces an ensemble of structures that satisfies translated restraints; and (4) the ensemble structure is analyzed and validated.
