Method DISTANCE GEOMETRY AND SIMULATED ANNEALING
Details 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FEBS LETT. 229, 129-136, USING THE PROGRAM XPLOR 3.1 ( BRUNGER) MODIFIED TO INCORPORATE DIPOLAR COUPLING RESTRAINTS (UNPUBLISHED). THE 3D STRUCTURE OF THE C-TERMINAL G26R MUTANT KH DOMAIN OF HNRNP K WAS SOLVED BY MULTI-DIMENSIONAL HETERONUCLEAR-EDITED AND -FILTERED NMR. IT IS BASED ON 1567 EXPERIMENTAL RESTRAINTS: 448 INTRARESIDUE, 322 SEQUENTIAL (|I-J|=1), 198 MEDIUM RANGE (1 < |I-J| >=5) AND 279 LONG RANGE (|I-J| >5) DISTANCE RESTRAINTS; 55 DISTANCE RESTRAINTS FOR 28 HYDROGEN BONDS; 49 DNH, 59 DCH, 48 DC'N, AND 53 DCAC' DIPOLAR COUPLING RESTRAINTS; 56 PHI-ANGLE RESTRAINTS FROM HN-HA COUPLING CONSTANTS. THE 20 STRUCTURES ARE ARRANGED IN ORDER OF INCREASING OVERALL ENERGY WITH MODEL 1 THE LOWEST. MODEL 9 HAS THE SMALLEST BACKBONE PAIRWISE RMS TO THE AVERAGE STRUCTURE.
