Abstract
The augmented ribbon model of a protein provides a way of describing features of its primary, secondary, and super-secondary structure. Associated with the model is a graph obtained by an ambient isotopy in space followed by a projection into the plane. This projection graph is shown to be independent of the ambient isotopy.
