    • 5 g/mol provides an estimate for the ratio of termination events to insertion events of 1:28900. Applying Boltzmann statistics to this ratio gives a ΔΔG‡ of 5.6 kcal/mol and an estimate for the termination barrier of 15.5-16.5 kcal/mol. In calculating ΔΔG‡ we have assumed that every hydrogen transfer event leads to the loss of the chain and, consequently, chain termination.

    • CM-N2-CA, Ni-N2-CA, and N2-CM-CT angle parameters were replaced by CM-N*-CT, H-N2-CA, and CM-CM-CT angle parameters of the AMBER95 force field, respectively. The X-N2-CM-X torsional parameters was replaced by the X-N2-CA-X parameter of the AMBER95 force field. The X-Ni-N2-X torsional parameter was assigned a barrier of zero.

    • 23 In the present case, one might expect a larger hysteresis due to the low-frequency modes of the ligands in the QM/MM simulation. In this case, however, the good agreement in the free energy barriers with static QM/ MM calculations indicates that the effect is small as well.
