Other Details THE COORDINATES DEPOSITED ARE FROM A COMBINED SAXS/EM STUDY. THE DOMAINS IN THE PROTEINS (HIGH RESOLUTION STRUCTURES FROM THE PDB) ARE POSITIONED RELATIVE TO ONE ANOTHER USING A SAXS CURVE, THIS COMPOSITE STRUCTURE IS THEN FITTED INTO AN EM MAP. MODEL GENERATED FROM SAXS REFINEMENT USING BUNCH. PETOUKHOV, M. V. AND SVERGUN, D. I. (2005). BIOPHYS J 89, 1237-50. SUBMISSION BASED ON EXPERIMENTAL DATA FROM EMDB EMD-1764. (DEPOSITION ID: 7401).

Fitting Procedure ?
Details METHOD--A MAP WAS GENERATED FROM THE SAXS MODEL COORDINATES AT A RESOLUTION MATCHING THE EXPERIMENTAL MAP. T HIS CALCULATED MAP WAS FITTED INTO THE EXPERIMENTAL MAP BY MAXIMIZING THE CROSS-CORRELATION WITH THE EXPERIMENTAL MAP. THE COORDINATES WERE THEN REPLACED IN THE CALCULATED MAP TO GENERATE THE FINAL ENTRY. REFINEMENT PROTOCOL--DOCKED USING CHIMERA
