  1. For each genome or phylogenetic group of genomes, we calculated the number of domains, distinct domain architectures, mean degree, mean clustering coefficient, network density (as a percentage of pairs that are connected) and the characteristic path length (each of these properties is defined [see Additional file 1]). The number of standard deviations between the randomised and observed graphs is included in parentheses. The parameters for all 192 genomes considered are provided [see Additional file 2].
