Our results showed that the MaC bond strength actually follows the trend Ni5Co5Fe, with differences of 10 and 80 kJ molÀ1, respectively. However, the reaction energies depend strongly on the methyl donor/acceptor, and it is therefore still possible that the methyl group binds directly to Ni in MCR, provided that the donor is properly activated [66]. 7 Metallation Reaction The use of Mg2þ in chlorophyll is quite unexpected, because Mg (in variance to Fe, Co, and Ni) strongly prefers O-ligands, rather than N-donors [85].

5). 5) kcal molÀ1. 6) kcal molÀ1. In this process, synchronously, the SaH bond of the glutathione is broken and a proton is transferred to the hydroxyl group of the selenenic acid accompanied by the formation of a SeaS bond. In the product, the seleno-sulfide adduct (EaSeaSG) and a water molecule (VI) are formed. 4) kcal molÀ1. Formation of EaSeaSG complex through selenosulfide linkage has been observed experimentally [19]. In the third and final elementary reaction, [EaSeaSG] þ GSH ! 6). We have explored several pathways for this reaction before suggesting the most plausible one.
