To assess potential effects depending on the local environment two distinct sites within the NCP were considered for 8oxoG insertion. In both cases, a highly pronounced relative difference in ∆A R→O of approximately 1 eV has been found between the wild-type and defect-containing systems. On the other hand, the analysis of 41 DNA structural properties showed that their average values on a 1 µs time scale at 300K differed very little between the wild-type and two defect systems. Further, the reorganization free energies, λ, differ only slightly between native and 8oxoG-containing NCPs (absolute relative changes of 0.13 eV and 0.01 eV respectively). This is consistent with the very small relative changes observed for solvent reorganization upon the oxidation of the native vs the defect systems (Figures and). It is also in line with the very similar and small RMSF differences reported in SI Tables and) for DNA bases belonging to the respective QM regions. Moreover, with the analysis of DNA-protein contacts within the QM region of all NCP systems in consideration (SI Tables and), it becomes clear that regardless of the exact position of the defect, the presence of the histone octamer has a minimal effect on the 8oxoG-induced changes of DNA redox properties in NCP. In addition, when compared to free, unpacked DNA, the smaller λ values reported herein demonstrate that the presence of the protein octamer further reduces possible relative structural differences upon oxidation.
