SOLUTION NMR Experimental Data


NMR Refinement
Details DETAILS OF THE STRUCTURE DETERMINATION AND ALL STRUCTURAL STATISTICS ARE GIVEN IN THE JRNL REFERENCE ABOVE. THE STRUCTURES ARE BASED ON 1135 INTERPROTON DISTANCE RESTRAINTS DERIVED FROM NOE MEASUREMENTS; AND 55 PHI, 44 PSI AND 45 CHI1 TORSION ANGLE RESTRAINTS DERIVED FROM COUPLING CONSTANTS AND NOE DATA, USING THE CONFORMATIONAL GRID SEARCH PROGRAM STEREOSEARCH (M. NILGES, G. M. CLORE, AND A. M. GRONENBORN, (1990) BIOPOLYMERS 29, 813. THE METHOD USED TO DETERMINE THE STRUCTURES IS THE HYBRID METRIC MATRIX DISTANCE GEOMETRY-DYNAMICAL SIMULATED ANNEALING METHOD (M. NILGES, G. M. CLORE, AND A. M. GRONENBORN, FEBS LETT. 229, 317-324 (1988)). A TOTAL OF 30 STRUCTURES WERE CALCULATED. AS THERE IS SOME UNCERTAINTY IN THE EXACT ORIENTATION OF THE N- AND C- TERMINAL FINGERS RELATIVE TO EACH OTHER, THE COORDINATES ARE PRESENTED TWICE. IN MODELS 1 THROUGH 30, THE COORDINATES ARE BEST FITTED TO THE N-TERMINAL DOMAIN (RESIDUES 2 - 28). IN MODELS 31 THROUGH 60, THE COORDINATES ARE BEST FITTED TO THE C-TERMINAL DOMAIN (RESIDUES 27 - 55). THE ANGLE BETWEEN THE LONG AXES OF THE HELICES (RESIDUES 13 - 25 AND 41 - 55 FROM THE N- AND C- TERMINAL FINGERS, RESPECTIVELY) ADOPT A RANGE OF VALUES CENTERED AROUND A MEAN OF 47 DEGREES WITH A STANDARD DEVIATION OF +/- 5 DEGREES. CONSEQUENTLY, NO AVERAGE STRUCTURE IS GIVEN. THE NUMBERS IN LAST COLUMN IN THE COORDINATE FILES HAVE NO MEANING. ALL THE INTERPROTON DISTANCE AND TORSION ANGLE RESTRAINTS ARE INCLUDED HERE AS A SEPARATE FILE: MBP_EXPT_DATA.DAT
