  We study the effects of electron-lattice interaction in the presence of
discrete breathers. The lattice is treated classically. We consider two
different situations - i) the scattering of an electron by a discrete breather
in the semiconducting regime, where the electron-breather distance is large
compared to the breather size, and ii) the appearance of a bound
electron-breather state, which exists at least over one half of the breather
period of oscillation. In the second case the localization length of the
electron can be of the order of the breather size - a few lattice periods.
Remarkably these results are derived in the absence of disorder, since discrete
breathers exist in translationally invariant nonlinear lattices.
