Properties of the main groups of regulons identified in the regulatory network of E. coli, based on average chromosomal distance between TF and its target genes
| Regulon group | Number of regulons (% of total regulons) | Regulon size (average no. of genes/regulon) | Total number of regulated genes (% of total regulated genes) | Average distance (in gene numbers) between the TF and the target genes | P-value significance (Z-score) |
|---|---|---|---|---|---|
| A | 10 (7%) | 76–399 (159) | 1595 (99) | 1059.45 | <0.001 (–9.98) |
| B | 73 (52%) | 2–48 (13) | 953 (59) | 889.69 | <0.001 (–10.74) |
| C | 58 (41%) | <12 (4.8) | 281 (17.5) | 2.42 | <0.001 (–20.44) |
