Abstract: 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.
Abstract: 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 observe that according to their structural roles, the nodes interact differently. By leading a community structure detection, we confirm this specific behavior and describe thecommunities composition to finally propose a new approach to fold a protein interaction network.
