✦ Synopsis
Recent reviews into the role of electron conduction within protein interactions have implicated the existence of soliton-like mechanisms that result in the conduction of electrons and bond vibrations along alpha-helix sections of proteins. This paper examines the possibility of solitons existing in other portions of a protein. It also investigates whether a soliton or exciton is implicated in vibrational signalling that may be used by biological systems to orchestrate bioprocesses as detailed by the Resonance Recognition Model.

For charge-transfer excitons strongly interacting with vibrations of a donor-acceptor chain, soliton-like states are found to have an internal structure: at a certain ratio of polaronic shift and electron-hole relative motion energy, a transition from a symmetric to a dimerized soliton occurs accomp
