REMARK 3 RESIDUAL DENSITY WAS OBSERVED AROUND RESIDUES B41 AND FITTED REMARK 3 WITH H2O MOLECULES. THESE WATER MOLECULES, HOWEVER, DO NOT FIT REMARK 3 THE 3.5A DISTANCE CRITERIA. THE DIFFERENCE DENSITY IS MOST REMARK 3 LIKELY CAUSED BY PEG MOLECULES AND NOT BY THE APPENDED REMARK 3 PEPTIDE. THE LAST RESIDUE OF MOLECULE A AND THE LAST FOUR REMARK 3 RESIDUES OF MOLECULE B WERE NOT CLEARLY IDENTIFIABLE IN THE REMARK 3 DIFFERENCE MAPS. A REFINEMENT WITH THE PROGRAM BUSTER SHOWED 3 REMARK 3 REMAINING RESIDUES OF MOLECULE B. THEIR OCCUPANCY, HOWEVER, REMARK 3 REFINED TO LOW VALUES AND WERE THEREFORE NOT INCLUDED IN THE REMARK 3 FINAL MODEL. COMBINATION OF CNS, BUSTER AND TNT USED FOR REMARK 3 REFINEMENT.
