distribution of degrees for HSN. The degree distribution of the
HSN for the whole data set is an exponential decrease law (Fig. 16)

¼ 0.97). Notice that the distribution is not anymore Gaussian-like in the whole proteins, and the
exponential decrease reflects the very special structure of the Hot
Spot Network. We already notice in [12, 19] that for interfaces
between two chains the degree distribution is exponential; this
means no hub in the interface but quite low degrees. For the
PCN, we find a Gaussian distribution, so this means considering
