| molecular dynamics | THE ORIENTATION OF THE PEPTIDE WITHIN THE MICELLE WAS DETERMINED FROM EXPERIMENTAL DATA (PARAMAGNETIC RELAXATION ENHANCEMENTS). THE RESTRAINT FILE CONTAINS DISTANCE RESTRAINTS FROM PEPTIDE ATOMS TO THE MICELLE CENTER, WHICH IS REPRESENTED AS THE PSEUDOATOM X, RESIDUE UNX. FIRST STEP: IN VACUO WITH NOVA FORCE FIELD. SECOND STEP: IN EXPLICIT SOLVENT (WATER/MICELLE) WITH YASARA FORCE FIELD. | TopSpin |
