abstract = {The structure and dynamics of all the transversion and
transition mismatches in three different DNA environments
have been characterized by molecular dynamics simulations
and NMR spectroscopy. We found that the presence of
mismatches produced significant local structural
alterations, especially in the case of purine transversions.
Mismatched pairs often show promiscuous hydrogen bonding
patterns, which interchange among each other in the
nanosecond time scale. This therefore defines flexible base
pairs, where breathing is frequent, and where distortions in
helical parameters are strong, resulting in significant
alterations in groove dimension. Even if the DNA structure
is plastic enough to absorb the structural impact of the
mismatch, local structural changes can be propagated far
from the mismatch site, following the expected
through-backbone and a previously unknown through-space
mechanism. The structural changes related to the presence of
mismatches help to understand the different susceptibility
of mismatches to the action of repairing proteins.},
