DATABASE POTENTIAL (KUSZEWSKI ET AL. (1996) PROTEIN SCI 5,

THE 3D STRUCTURE OF THE N-TERMINAL DOMAIN OF HIV-1
INTEGRASE WAS SOLVED BY
MULTI-DIMENSIONAL HETERONUCLEAR-EDITED AND -FILTERED NMR
IS BASED ON 851 EXPERIMENTAL RESTRAINTS (PER MONOMER):
(A) INTRASUBUNIT: 201 SEQUENTIAL (|I-J|=1), 224 MEDIUM
RANGE (1 < |I-J| >=5) AND 98 LONG RANGE (|I-J| >5)
INTERRESIDUE, AND 17 INTRARESIDUE APPROXIMATE INTERPROTON
DISTANCE RESTRAINTS; 32 DISTANCE RESTRAINTS FOR 16
HYDROGEN BONDS; 91 TORSION ANGLE (45 PHI, 1 PSI, 31 CHI1
AND 14 CHI2) RESTRAINTS; 40 THREE-BOND HN-HA COUPLING
CONSTANT RESTRAINTS; 97 (50 CALPHA AND 47 CBETA) 13C
SHIFT RESTRAINTS.
(B) 28 INTERSUBUNIT INTERPROTON DISTANCE RESTRAINTS.
(C) 23 AMBIGUOUS INTERPROTON DISTANCE RESTRAINTS THAT
CAN ARISE FROM INTRA AND/OR INTERSUBUNIT INTERACTIONS.
THE STRUCTURES IN THIS ENTRY ARE THE 40 SIMULATED ANNEALING
STRUCTURES. THE LAST NUMERIC COLUMN IN THE INDIVIDUAL SA
STRUCTURES HAS NO MEANING. THE LAST LETTER COLUMN
SIGNIFIES THE SUBUNIT (A OR B). RESIDUES 47 - 55 ARE
DISORDERED. | X-PLOR |
