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. THIS MODEL IS THE RESULT OF RESTRAINED ENERGY MINIMIZATION OF THE GEOMETRIC MEAN OF 20 STRUCTURES FROM THE ENSEMBLE (ENTRY 1ILP) SEE JRNL ENTRY FOR MORE DETAILS. | ||||||||||||
