A computationally efficient hybrid-hybrid relaxation matrix refinement methodology using 3D NOESY-NOESY data is described. The methodology was tested on simulated data, derived from the Dickerson dodecamer, and used to refine the structure of a DNA three way junction from experimentally determined 3D NOESY-NOESY volume data. Our results indicate that the 3D hybrid-hybrid MORASS methodology, by combining the spectral dispersion of 3D NOESY-NOESY spectroscopy and the computational efficiency of 2D refinement programs, provides an accurate and robust means for structure determination of large biomolecules.
