Method RIGID BODY MINIMIZATION FOLLOWED BY RESTRAINED SIMULATED ANNEALING
Details STRUCTURES WERE CALCULATED USING XPLOR-NIH. REFINEMENTS WERE CARRIED OUT FIRST BY RIGID BODY MINIMIZATION (CLORE(2000) PROC.NATL.ACAD.SCI. 97, 9021-9025) FOLLOWED BY RESTRAINED SIMULATED ANNEALING (WANG ET AL. EMBO J. (2000) 19,5635-5649). THE CRYSTAL STRUCTURE OF THE COMPLEX BY BODE ET AL. (NATURE (1997), 389, 77-81; PDB CODE: 1UEA) HAS BEEN USED AS A STARTING POINT WITH PROTONS ATTACHED AND TAKING ONLY N-TERMINAL 126 RESIDUES OF TIMP-1. INTERFACIAL SIDE CHAINS OF THE FOLLOWING RESIDUES WERE ALLOWED TO BE FLEXIBLE: CHAIN A (MMP-3(DC)): 162-169,198-202, 205-206, 211 AND 221-223; CHAIN B (N-TIMP-1): 302-304, 329, 333-335,366-369; A TOTAL OF 49 NOE (46 INTERMOLECULAR AND 3 INTRAMOLECULAR) 75 NH DIPOLAR COULINGS FOR N-TIMP-1, 19 NH DIPOLAR COUPLINGS AND 8 CaHa DIPOLAR COUPLINGS FOR MMP-3 WERE USED FOR REFINEMENT. TARGET FUNCTIONS INCLUDE TERMS FOR NOE RESTRAINTS, DIPOLAR COUPLING RESTRAINTS AND RADIUS OF GYRATION. ALSO, MODULE ( DOSSET ET AL. J. BIOMOL. NMR, (2001),20,223-231) AND PALES (ZWECKSTETTER AND BAX, J. AM. CHEM. SOC (2000), 122, 3791-3792) WERE USED FOR EVALUATING THE ORIENTATION AND STRUCTURES.
