A General Model for Amino Acid Interaction Networks

Authors: Omar GACI, Stefan BALEV


In this paper we introduce the notion of protein interaction network. This is a graph whose vertices are the protein-s amino acids and whose edges are the interactions between them. Using a graph theory approach, we identify a number of properties of these networks. We compare them to the general small-world network model and we analyze their hierarchical structure.

Keywords: protein structure, small-world network, interaction network
