Before revision:  We employ this method to identify the representations of proteinsthat entail the largest amount of information from the original systems. It is shown that representations with low values of mapping entropy share common features that are intrinsically related to the biological properties of the proteins under examination, thereby establishing a bridge between protein structure, energetics, and function.
