NMR Refinement
Method DISTANCE GEOMETRY AND SIMULATED ANNEALING
Details THE STRUCTURE OF APOC-I(1-38) IN THE PRESENCE OF SODIUM DODECYL SULFATE WAS REFINED USING 685 NOE-BASED DISTANCE RESTRAINTS. NO DIHEDRAL RESTRAINTS AND NO H-BOND RESTRAINTS WERE USED. THIS ENTRY CONTAINS 18 ACCEPTED OUT OF 50 CALCULATED STRUCTURES. STRUCTURE CALCULATIONS WERE PERFORMED WITH THE PROGRAMS DGII AND DISCOVER INCLUDING DISTANCE GEOMETRY CALCULATIONS, SIMULATED ANNEALING AND ENERGY MINIMIZATION WITH A CONJUGATED GRADIENT. THE CVFF FORCEFIELD WAS USED. ALL FORMAL CHARGES WERE SWITCHED OF. THE DIELECTRIC CONSTANT WAS SET TO 1. THE LENNARD-JONES POTENTIAL WAS USED FOR NON-BOND INTERACTIONS (CUTOFF 12A). FOR DETAILS ON STRUCTURE CALCULATION, RMSDS AND FINAL ENERGIES PLEASE SEE REFERENCE CITED UNDER "JRNL".
