CONSTRAINED SCATTERING FITTING OF HOMOLOGY MODELSINSIGHT II, HOMOLOGY, DISCOVERY, BIOPOLYMER, DELPHI, O, SCTPL7, GNOMACCELRYS100001THE MODELLED SCATTERING CURVES WERE ASSESSED BY CALCULATION OF THE RG, RSX-1 AND VALUES IN THE SAME Q RANGES USED IN THE EXPERIMENTAL GUINIER FITS. MODELS WERE THEN RANKED USING A GOODNESS-OF-FIT R-FACTOR DEFINED BY ANALOGY WITH PROTEIN CRYSTALLOGRAPHY1HOMOLOGY MODELS WERE BUILT FOR THE CYS-BOX, WAP AND FOUR FNIII DOMAINS. THE POSITIONS OF THE DOMAINS WERE DETERMINED BY AN APPROACH THAT COMBINED RAND ...HOMOLOGY MODELS WERE BUILT FOR THE CYS-BOX, WAP AND FOUR FNIII DOMAINS. THE POSITIONS OF THE DOMAINS WERE DETERMINED BY AN APPROACH THAT COMBINED RANDOMISED LINKER PEPTIDE STRUCTURES PRODUCED BY MOLECULAR DYNAMICS SIMULATIONS WITH CURVE-FITTING TO EXPERIMENTAL X-RAY SOLUTION SCATTERING DATA. A SINGLE ARRANGEMENT OF THE SIX DOMAINS IS PRESENTED, WHICH IS REPRESENTATIVE OF A FAMILY OF STRUCTURES THAT FIT THE SCATTERING DATA. MORE DETAILS ON THE MODELLING STRATEGY ARE CONTAINED IN THE PRIMARY REFERENCE. THE ALGORITHM RESULTED IN SEVERAL CLOSE APPROACHES BETWEEN ATOMS. THIS ENTRY CONTAINS FOUR SUCH PAIRS ALA 292 - PRO 318 PRO 291 - GLU 319 PRO 27 - PHE 122 TYR 225 - PHE 355
