    • The ps components for dTTP, dGTP, and dCTP were 10-40% longer than in the corresponding complexes with Ap while for dATP a slightly shorter ps component (266 ps) was found. These differences can be attributed to variations in the complex structure. Only the Ap-R/dITP system did not exhibit the ps component.

    • The small amplitude of the ps component and the fact that this component is absent when Ap is replaced by Ap-R shows that complexes with dITP are very sensitive to structural parameters and have weak binding energies. This observation is consistent with the small exothermicity that we propose for either hole or electron transfer from Ap* to I.
