MODELS WERE THEN RANKED USING A GOODNESS-OF-FIT R-FACTOR DEFINED BY ANALOGY WITH PROTEIN CRYSTALLOGRAPHY AND BASED ON THE EXPERIMENTAL CURVES IN THE Q RANGE EXTENDING TO 2.2 NM-1 (X-RAYS) AND 1.12 NM-1 (ILL NEUTRONS). 詳細: HOMOLOGY MODELS WERE BUILT FOR THE 5 SCR DOMAINS AND ENERGY MINIMISATIONS WERE PERFORMED TO IMPROVE THE CONNECTIVITY IN THE FH MODEL.

BIANTENNARY COMPLEX-TYPE CARBOHYDRATE STRUCTURES (MAN3GLCNAC4GAL2FUC0NEUNAC2) WERE ADDED TO EACH OF THE N-LINKED GLYCOSYLATION SITES. A LIBRARY OF LINKER PEPTIDE CONFORMATIONS WAS USED IN DOMAIN MODELLING CONSTRAINED BY THE SOLUTION SCATTERING FITS. MODELLING WITH THE SCATTERING DATA WAS ALSO CARRIED OUT BY ROTATIONAL SEARCH METHODS. THE X-RAY AND NEUTRON SCATTERING CURVE I(Q) WAS CALCULATED ASSUMING A UNIFORM SCATTERING DENSITY FOR THE SPHERES USING THE DEBYE EQUATION AS ADAPTED TO SPHERES. X-RAY CURVES WERE CALCULATED FROM THE HYDRATED SPHERE MODELS WITHOUT CORRECTIONS FOR WAVELENGTH SPREAD OR BEAM DIVERGENCE, WHILE THESE CORRECTIONS WERE APPLIED FOR THE NEUTRON CURVES BUT NOW USING UNHYDRATED MODELS.
