CONJOINED RIGID BODY/TORSION ANGLE SIMULATED ANNEALING DYNAMICS	THE STRUCTURES WERE CALCULATED BY CONJOINED RIGID BODY/TORSION ANGLE DYNAMICS (SCHWIETERS & CLORE (2001) J.MAGN.RESON 152, 288-302). THE TARGET FUNCTIONS COMPRISES TERMS FOR NOE RESTRAINTS, SIDECHAIN TORSION ANGLE RESTRAINTS, RESIDUAL DIPOLAR COUPLING RESTRAINTS (CLORE ET AL. J.MAGN.RESON. 131, 159-162 (1998); J.MAGN.RESON.133, 216-221(1998)), A RADIUS OF GYRATION TERM (KUSZEWSKI ET AL. J.AM.CHEM.SOC. 121, 2337-2338 (1999)), A QUARTIC VAN DER WAALS REPULSION TERM (NILGES ET AL. (1988) FEBS LETT. 229, 129-136), AND A TORSION ANGLE CONFORMATIONAL DATABASE POTENTIAL OF MEAN FORCE (CLORE AND KUSZEWSKI 2002) J.AM.CHEM.SOC 124, 2866-2867). THE STARTING COORDINATE COME FROM THE NMR STRUCTURE OF THE BAF DIMER (1QCK; KUSZEWSKI ET AL. J.AM.CHEM.SOC.121, 2337-2338(1999)) AND THE LEM-DOMAIN OF EMERIN (PDB ID 2ODC; CAI ET AL) THE BACKBONE COORDINATES AND NON-INTERFACIAL SIDECHAINS ARE TREATED AS RIGID BODIES THROUGHOUT WITH THE BAF DIMER HELD FIXED, THE MOLECULES ALLOWED TO ROTATE AND TRANSLATE, AND THE AXIS OF THE SINGLE DIPOLAR COUPLING ALIGNMENT TENSOR FREE TO ROTATE. THE INTERFACIAL SIDECHAINS ARE GIVEN FULL TORSIONAL DEGREES OF FREEDOM.	X-PLOR NIH
