RESTRAINED MOLECULAR DYNAMICS INITIAL COORDINATES FOR IL-8 WERE TAKEN FROM PDB ENTRY 1IL8; A LINEAR CHAIN FOR THE CXCR-1 FRAGMENT WAS BUILT IN INSIGHT (MSI). THE CXCR-1 FRAGMENT WAS POSITIONED RANDOMLY WITH RESPECT TO IL8 - OBTAIN 40 STARTING CONFORMATIONS. THE INITIAL STRUCTURES WERE THEN REFINED USING RMD WITH THE AMBER ALL ATOM FORCE FIELD AS IMPLIMENTED WITHIN DISCOVER. ALL OF IL8 MONOMER B AND PARTS OF IL8 MONOMER A (2-7, 22-38 AND 51-72) WERE KEPT FIXED DURING THE REFINEMENT SINCE CHEMICAL SHIFT CHANGES INDICATED THAT THESE PORTION OF THE MOLECULE WERE NOT PERTURBED BY PEPTIDE BINDING.
