Examples of the different configurations observed in dinuclear sites. (a) A homonuclear nickel site with an exogenous molecule and a carboxylate coordinating the two metal ions (PDB entry 4gsv), (b) a homonuclear copper site with two bridging water molecules (PDB entry 1ll1), (c) zinc(II) and copper ions separated by a histidinate (PDB entry 1sos) and (d) a heteronuclear site of iron and manganese within the porphyrin framework (PDB entry 2boq). |
