DISTANCE GEOMETRY/SIMULATED ANNEALING/RELAXATION MATRIX REFINEMENT	THE STRUCTURE OF APOC-II(44-79) IN THE PRESENCE OF SODIUM DODECYL SULFATE WAS REFINED USING A RELAXATION MATRIX REFINEMENT PROTOCOL BASED ON 241 NOESY CROSS- PEAK INTENSITIES MEASURED AT SEVEN DIFFERENT NOESY MIXING TIMES BETWEEN 75 MS AND 300 MS. NO DIHEDRAL RESTRAINTS WERE USED. THIS ENTRY CONTAINS 19 ACCEPTED STRUCTURES. ONE CALCULATED STRUCTURE WAS REJECTED BECAUSE OF HIGH COVALENT ENERGY. STRUCTURE CALCULATIONS WERE PERFORMED WITH THE PROGRAM X-PLOR (AXEL BRUNGER) INCLUDING DISTANCE GEOMETRY CALCULATIONS, SIMULATED ANNEALING (BOTH UNDER THE ISOLATED SPIN PAIR APPROXIMATION AND COMPLETE RELAXATION MATRIX CALCULATIONS) AS WELL AS ENERGY MINIMIZATION WITH A CONJUGATED GRADIENT. THE CHARMM FORCEFIELD WAS USED. FOR DETAILS ON STRUCTURE CALCULATION PLEASE SEE REFERENCE CITED UNDER "JRNL".	1
