BOND RESTRAINTS FOR THE CO MOLECULE, HIS 93 AND FOR THE PYRROLE NITROGEN TO THE IRON ATOM WERE WEAKENED FROM THE STANDARD X-PLOR VALUES (PARAM19X.HEME). THERE IS NEARLY NO ELECTRON DENSITY FOR THE N-FORMYL-MET. THIS RESIDUE WAS NOT INCLUDED INTO THE MODEL. ELECTRON DENSITY FEATURES CLOSE TO THIS SITE WERE MODELED BY WATER MOLECULES. ONE TREHALOSE MOLECULE IS BOUND TO THE SURFACE OF THE MYOGLOBIN MOLECULE. THE WATER MOLECULES NUMBER 246 AND 252 ARE ON OR CLOSE TO SPECIAL POSITIONS.
