Atom site foot note | 1: RESIDUE PRO 74 IS A CIS-PROLINE. 2: AN OCCUPANCY OF 0.0 DENOTES ATOMS THAT HAVE NOT BEEN LOCALIZED IN THE ELECTRON DENSITY. 3: THIS HALF OCCUPIED WATER MOLECULE IS THE *SIXTH* LIGAND IN THE REDUCED DEOXY FORM. IT IS LOCATED APPROXIMATELY AT THE SAME POSITION AS THE WATER OF THE AQUO MET FORM 3 ANGSTROMS APART FROM THE IRON. |
