Table 1. Abundance of three-node subgraphs in the TR network of E. coli and the randomized version of this network
Subgraph CNV DIV CAS FFL
Abundance in real network 227 4777 160 42
Abundance in randomized network 231.92 ± 8.05 4339.3 ± 132 186.69 ± 7.08 9.50 ± 4.17
z score 0.61 3.31 3.77 7.79
  • The corresponding z scores (13) (listed in the bottom row) indicate the deviation of the values for the real network from those for the randomized network. The corresponding distributions are shown in Fig. 6.
