REMARK 3 PROGRAM : GROMACS 1.6 REMARK 3 AUTHORS : VAN DER SPOEL, D.; VAN BUUREN, A.R.; APOL, E.; REMARK 3 MEULENHOFF, P.J.; TIELMAN, D.P.; SIJBERS, REMARK 3 A.L.T.M.; VAN DRUNEN, R.; BERENDSEN, H.J.C. REMARK 3 REMARK 3 OTHER REFINEMENT REMARKS: THE STRUCTURES OF CCK-A-R(1-47) AND REMARK 3 CCK-8 WERE CALCULATED SEPARATELY. THE COMPLEX WAS CALCULATED REMARK 3 USING INTRA- AND INTERMOLECULAR NOES USING SIMULATED ANNEALING REMARK 3 AND MOLECULAR DYNAMICS CALCULATIONS. THE CALCULATIONS UTILIZED REMARK 3 EXPLICIT SOLVENT, AS A DECANE/WATER SIMULATION CELL.
