REMARK 3 PROGRAM : X-PLOR NIH (HTTP://NMR.CIT.NIH.GOV/XPLOR_NIH) REMARK 3 AUTHORS : CLORE, KUSZEWSKI, SCHWIETERS, TJANDRA REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE STRUCTURES WERE CALCULATED BY REMARK 3 CONJOINED RIGID BODY/TORSION ANGLE DYNAMICS (SCHWIETERS & CLORE REMARK 3 (2001) J.MAGN.RESON 152, 288-302). THE TARGET FUNCTIONS REMARK 3 COMPRISES TERMS FOR NOE RESTRAINTS, SIDECHAIN TORSION ANGLE REMARK 3 RESTRAINTS, RESIDUAL DIPOLAR COUPLING RESTRAINTS (CLORE ET AL. REMARK 3 J.MAGN.RESON. 131, 159-162 (1998); J.MAGN.RESON.133, 216- REMARK 3 221(1998)), A RADIUS OF GYRATION TERM (KUSZEWSKI ET AL.(1999), A REMARK 3 QUARTIC VAN DER WAALS REPULSION TERM (NILGES ET AL. (1988) FEBS REMARK 3 LETT. 229, 129- 136), AND A TORSION ANGLE CONFORMATIONAL REMARK 3 DATABASE POTENTIAL OF MEAN FORCE (CLORE AND KUSZEWSKI 2002) REMARK 3 J.AM.CHEM.SOC 124, 2866-2867). THE STARTING COORDINATE COME FROM REMARK 3 THE X-RAY STRUCTURES (WITH PROTONS ADDED) OF E. COLI HPR (1POH, REMARK 3 JIA ET AL. (1993) J.BIOL.CHEM. 268, 22940-22501, RESOLUTION 2.0 REMARK 3 A); AND IIAMAN (1PDO, NUNN ET AL. (1996) J.MOL.BI J.MOL.BIOL. REMARK 3 259, 502-511; RESOLUTION 1.7A). THE BACKBONE COORDINATES AND NON- REMARK 3 INTERFACIAL SIDECHAINS ARE TREATED AS RIGID BODIES THROUGHOUT REMARK 3 WITH THE IIAMAN DIMER HELD FIXED, THE TWO HPR MOLECULES ALLOWED REMARK 3 TO ROTATE AND TRANSLATE, AND THE AXIS OF THE SINGLE DIPOLAR REMARK 3 COUPLING ALIGNMENT TENSOR FREE TO ROTATE. THE INTERFACIAL REMARK 3 SIDECHAINS ARE GIVEN FULL TORSIONAL DEGREES OF FREEDOM. REMARK 4 REMARK 4 1VRC COMPLIES WITH FORMAT V. 3.15, 01-DEC-08 REMARK 7 REMARK 7 IN THIS ENTRY THE LAST COLUMN REPRESENTS THE AVERAGE RMS REMARK 7 DIFFERENCE BETWEEN THE INDIVIDUAL SIMULATED ANNEALING REMARK 7 STRUCTURES AND THE MEAN COORDINATE POSITIONS. IT IS REMARK 7 IMPORTANT TO NOTE THAT THE VALUES GIVEN FOR THE BACKBONE REMARK 7 ATOMS AND NON-INTERFACIAL SIDECHAINS PROVIDE ONLY A REMARK 7 MEASURE OF THE PRECISION WITH WHICH THE RELATIVE REMARK 7 ORIENTATION OF THE TWO PROTEINS HAVE BEEN DETERMINED AND REMARK 7 DOES NOT TAKE INTO ACCOUNT THE ERRORS IN THE X-RAY REMARK 7 COORDINATES OF HPR AND IIAMAN. REMARK 7 RESIDUE NUMBERING: REMARK 7 IIAMAN: 1-136 (THE N-TERMINAL METHIONINE IS CLEAVED AND REMARK 7 RESIDUES 131-136 WERE DISORDERED. RESIDUES 134-136 ARE REMARK 7 CLONING ARTIFACTS; SEE REMARKS IN THE REMARK 7 1PDO CRYSTAL STRUCTURE.) REMARK 7 HPR: 201-285 (CORRESPONDING TO RESIDUES 1-85). REMARK 7 PHOSPHATES: RESIDUES 401 AND 402. REMARK 7 TWO SETS OF COORDINATES ARE GIVEN: REMARK 7 MODEL 1: RESTRAINED REGULARIZED MEAN COORDINATES FOR THE REMARK 7 MODEL OF THE ASSOCIATIVE PHOSPHORYL TRANSITION STATE REMARK 7 HPR-IIAMTL COMPLEX. EXPERIMENTAL RESTRAINTS ARE REMARK 7 IDENTICAL TO THOSE USED FOR MODEL 2, BUT COVALENT REMARK 7 GEOMETRY RESTRAINTS ARE INCLUDED RELATING TO THE REMARK 7 PENTACOORDINATE PHOSPHORYL GROUP IN A TRIGONAL BIPYRAMIDAL REMARK 7 GEOMETRY. THE STRUCTURE IS DERIVED FROM REMARK 7 MODEL 2 BY RESTRAINED REGULARIZATION IN WHICH ONLY REMARK 7 THE ACTIVE SITE HISTIDINES, THE BACKBONE IMMIEDIATELY REMARK 7 ADJACENT (ONE RESIDUE ON EITHER SIDE) TO THE ACTIVE SITE REMARK 7 HISTIDINES, AND THE INTERFACIAL SIDECHAINS ARE ALLOWED TO REMARK 7 MOVE. THE N-P BOND LENGTHS ARE RESTRAINED TO 2 A. REMARK 7 IIAMAN-HPR COMPLEX REMARK 7 RMS DEVIATIONS FROM NOE DISTANCE RESTRAINTS: 0.009 A REMARK 7 RMS DEVIATIONS FROM SIDECHAIN TORSION ANGLE RESTRAINTS: REMARK 7 0.0 DEG.

REMARK 7 WAS USED FOR THE DIPOLAR COUPLINGS (CLORE AND GARRETT REMARK 7 (1999) J. AM. CHEM. SOC. 121, 9008-9012). REMARK 7 NOTE THE NH DIPOLAR COUPLINGS FOR FULLY BOUND HPR REMARK 7 (I.E. BOTH BIDNING SITES ON IIAMAN FULLY SATURATED) REMARK 7 ARE BACKCALCULATED FROM THE DIPOLAR COUPLINGS MEASURED REMARK 7 FOR A SAMPLE WITH A THREE-FOLD MOLAR EXCESS OF HPR REMARK 7 OVER IIAMAN BINDING SITES AND A SAMPLE OF FREE HPR. REMARK 7 THE FIRST VALUE OF THE R-FACTOR USES DIPOLAR COUPLINGS REMARK 7 FOR THE FULLY BOUND STATE BACK-CALCULATED USING THE MEASURED REMARK 7 VALUES OF THE DIPOLAR OUPLINGS FOR FREE HPR; WHILE REMARK 7 THE SECOND NUMBER USES THE CALCULATED VALUES OF THE DIPOLAR REMARK 7 COUPLINGS FOR FREE HPR DERIVED FROM THE MEASURED VALUES REMARK 7 AND THE CRYSTAL STRUCTURE OF FREE HPR USING SINGULAR VALUE REMARK 7 DECOMPOSITION. NOTE A SINGLE ALIGNMENT TENSOR IS USED. REMARK 7 THE DIPOLAR COUPLING R-FACTOR OBTAINED BY SINGULAR VALUE REMARK 7 DECOMPOSITION AGAINST THE CRYSTAL STRUCTURES OF IIAMAN REMARK 7 AND HPR INDIVIDUAL ARE THE SAME AS THOSE OBTAINED FOR THE REMARK 7 COMPLEX AS A WHOLE.
