Comparative Study of Elastic Network Model and Protein Contact Network for Protein Complexes: The Hemoglobin Case

Figure 3

Modular analysis of -Hb based on GNM. (a) The correlation map corresponding to the first mode divides the Hb into two modules. Red regions correspond to collective residue motions and blue-colored regions correspond to uncorrelated motions. (b) The shape of the first mode, which not only shows two modules but also predicts hinge sites.
