simulated annealing	THE STRUCTURES WERE CALCULATED USING THE SIMULATED ANNEALING PROTOCOL OF NILGES ET AL. (1988) FEBS LETT. 229, 129-136, USING THE PROGRAM XPLOR 3.1 (BRUNGER) MODIFIED TO INCORPORATE COUPLING CONSTANT (GARRETT ET AL. (1984) J. MAGN RESON. SERIES B 104, 99-103), CARBON CHEMICAL SHIFT (KUSZEWSKI ET AL. (1995) J. MAGN. RESON. SERIES B 106, 92-96) RESTRAINTS AND A CONFORMATIONAL DATABASE POTENTIAL (KUSZEWSKI ET AL. (1996) PROTEIN SCI 5, 1067-1080 AND (1997) J. MAGN. RESON. 125, 171-177). THE 3D STRUCTURE OF THE N-TERMINAL DOMAIN OF THE H12C MUTANT OF HIV-1 INTEGRASE COMPLEXED TO CADMIUM WAS SOLVED BY MULTI-DIMENSIONAL HETERONUCLEAR-EDITED AND -FILTERED NMR IS BASED ON 757 EXPERIMENTAL RESTRAINTS (PER MONOMER): (A) INTRASUBUNIT: 203 SEQUENTIAL (\|I-J\|=1), 161 MEDIUM RANGE (1 < \|I-J\| >=5) AND 82 LONG RANGE (\|I-J\| >5) INTERRESIDUE, AND 5 INTRARESIDUE APPROXIMATE INTERPROTON DISTANCE RESTRAINTS; 16 DISTANCE RESTRAINTS FOR 8 HYDROGEN BONDS; 117 TORSION ANGLE (45 PHI, 35 PSI, 26 CHI1, 10 CHI2 AND 1 CHI3) RESTRAINTS; 47 THREE-BOND HN-HA COUPLING CONSTANT RESTRAINTS; 99 (50 CALPHA AND 49 CBETA) 13C SHIFT RESTRAINTS. (B) 20 INTERSUBUNIT INTERPROTON DISTANCE RESTRAINTS. (C) 7 AMBIGUOUS INTERPROTON DISTANCE RESTRAINTS THAT CAN ARISE FROM INTRA AND/OR INTERSUBUNIT INTERACTIONS.
