  Recent papers have considered moving breathers (MBs) in DNA models including
long range interaction due to the dipole moments of the hydrogen bonds. We have
recalculated the value of the charge transfer when hydrogen bonds stretch using
quantum chemical methods which takes into account the whole nucleoside pairs.
We explore the consequences of this value on the properties of MBs, including
the range of frequencies for which they exist and their effective masses. They
are able to travel through bending points with fairly large curvatures provided
that their kinetic energy is larger than a minimum energy which depends on the
curvature. These energies and the corresponding velocities are also calculated
in function of the curvature.
