Nanonetworks of amino acids: A two-level topological description

In this paper, we study nanonetworks of amino acid interaction networks. This is a graph whose vertices are the proteins amino acids and whose edges are the interactions between them. We propose two steps to the study of such interaction networks. We begin by a top-down approach where the graphs are characterized by topological metrics. We continue by a bottom-up approach where the collective interactions of the nanomachines contribute to the emergence of the global topological behavior. Both studies show that the topological features of the studied nanonetworks are deduced from the structural properties of proteins.
