The mechanism for energy and signal transport in proteins as suggested by Davydov is discussed. The idea is based on a coupling of amide-I oscillators to acoustic phonons in a hydrogen bonded chain. Results as obtained with the usually used ansätze are discussed. The quality of these states for an approximate solution of the time-dependent Schrödinger equation is investigated. It is found that the semiclassical ansatz is a poor approximation, while the more sophisticated |D1> state seems to…

The authors' simulations indicate that the excitation frequently becomes localized on the end of the helix due to the defect in helical structure caused by unwinding, and generally do not support the existence of Davydov type solitons in biological helix systems under physiological conditions.
