MODELS WERE THEN RANKED USING A GOODNESS-OF-FIT CHI SQUARE-FACTOR DEFINED BY THE DIFFERENCE BETWEEN THE CALCULATED AND EXPERIMENTAL SCATTERING INTENSITIES AND BASED ON THE EXPERIMENTAL CURVES IN THE Q RANGE EXTENDING TO 2.4 NM-1 (PROTEIN) AND 2.1 NM-1 (LIPID). Details: AN ALL ATOM COMPUTATIONAL MODEL WAS CONSTRUCTED BY COMBINING MOLELING WITH CONRAST VARIATION SANS, HYDROGEN-DEUTERIUM EXCHANGE (H/D-MS/MS), AND DISTANCE CONSTRAINTS FROM CROSS-LINKING, ...Details: AN ALL ATOM COMPUTATIONAL MODEL WAS CONSTRUCTED BY COMBINING MOLELING WITH CONRAST VARIATION SANS, HYDROGEN-DEUTERIUM EXCHANGE (H/D-MS/MS), AND DISTANCE CONSTRAINTS FROM CROSS-LINKING, FLUORESCENCE RESONANCE ENERGY TRANSFER AND ELECTRON SPIN RESONANCE. SANS LOW RESOLUTION STRUCTURES (12% AND 42% D2O) WERE USED AS SCAFFOLDS TO BUILD MOLECULAR MODELS FOR PROTEIN AND LIPID COMPONENTS OF NASCENT HDL. 256 MODELS WERE GENERATED AND ASSESSED USING GOODNESS-OF-FIT WITH BOTH SANS AND H/D-MS/MS DATA. THE NEUTRON SCATTERING CURVE I(Q) WAS CALCULATED ASSUMING ALL ATOM STRUCTURE, AND WITH CORRECTIONS FOR WAVELENGTH SPREAD AND BEAM DIVERGENCE.
