A model for the resistance of the proton channel formed by the proteolipid of ATPase

The conductance observed for single proton channels formed by proteolipids of ATPase (Schindler and Nelson 1982) is rationalized in terms of a hydrogen bonded network model. A simple algebraic expression for the resistance predicted for such a model is presented and the results are compared to the experimental observations. The comparision suggests that the conduction involves a series of bound water molecules and perhaps amino acid side groups.
