Data:
The regulatory network for Yeast and E. coli. The file is in a tab-delimited format with the regulator followed by the target in the same line. For E. coli, the last column also list the type of regulation: "+" for positive, "-" for negative and "+-" for dual regulation. For E. coli, the transcriptional regulatory network was obtained from RegulonDB (as of July 2009) (S. Gama-Castro et al., Nucleic Acids Res 36, D120, 2008). For S. cerevisiae, the data was obtained from various biochemical and genetic experiments (T. I. Lee et al., Science 298, 799, 2002, C. T. Harbison et al., Nature 431, 99, 2004, C. E. Horak et al., Genes Dev 16, 3017, 2002, V. V. Svetlov, T. G. Cooper, Yeast 11, 1439, 1995).
| Yeast | E. coli | |
|---|---|---|
| Number of regulatory interactions | 12873 | 3123 |
| Number of Regulators | 288 | 143 |
| Number of Targets | 4410 | 1420 |
| Number of Inter-Regulator interactions | 632 | 220 |
Assignment into hierarchies for Yeast and E. coli.
Changes in hierarchies:
Yeast Gene Deletion from Deutschbauer et al. Columns are as follows:
Column 1: Delete: the gene deleted
Column 2: Current_level: the position in the wild-type hierarchy. Bottom=Level 1. First = Level 2. Two = Level 3. Three = Level 4.
Column 3: Out_TF: the number of TFs it regulates. Equals 0 for all bottom level rgulators.
Column 4: Out_overall: the total number of targets
Column 5: In: In-degree, the number of its regulators
Column 6: Het: tag fitness of the heterozygous deletion in ypd
Column 7: Hom: tag fitness of the homozygous deletion in ypd
Column 8: Ave_hom_het: average fitness of the homozygous and heterozygous deletion in ypd
Column 9: Changes: the number of changes in the hierarchy upon deletion of that gene.
The next set of 3 columns are as follows:
Column 10, 13, 16 etc: Gene_moved: gene that moved its position in the hierarchy
Column 11, 14, 17 etc: Initial_level: its initial level in the WT hierarchy
Column 12, 15, 18 etc:Final_level: its final position in the rearranged hierarchy.
Yeast gene deletion from Synthetic array by Costanzo et al. Columns are as follows:
Column 1: Deleted1: first gene deleted.
Column 2: Deleted2: second gene deleted.
Column 3: level1: first gene's position in the wild-type hierarchy. Bottom=Level 1. First = Level 2. Two = Level 3. Three = Level 4.
Column 3: level2: second gene's position in the wild-type hierarchy. Bottom=Level 1. First = Level 2. Two = Level 3. Three = Level 4.
Column 5: P-value: P-value of the genetic interaction between them.
Column 6: Pheno: cell growth upon deletion of that pair.
Column 7: Changes: the number of changes in the hierarchy upon deletion of that pair.
The next set of 3 columns are as follows (empty if the number of changes =0):
Column 8, 11, 14 etc: Gene_moved: gene that moved its position in the hierarchy.
Column 9, 12, 15 etc: Initial_level: its initial level in the WT hierarchy.
Column 10, 13, 16 etc:Final_level: its final position in the rearranged hierarchy.
E. coli gene deletion from Baba et al. Columns are as follows:
Column 1: Delete: the gene deleted
Column 2: Current_level: the position in the wild-type hierarchy. Bottom=Level 1. First = Level 2. Two = Level 3. Three = Level 4.
Column 3: Out_TF: the number of TFs it regulates. Equals 0 for all bottom level rgulators.
Column 4: Out_overall: the total number of targets
Column 5: Colonies: the fraction of colonies that survived.
Column 6: Changes: the number of changes in the hierarchy upon deletion of that gene.
The next set of 3 columns are as follows:
Column 7, 10, 13 etc: Gene_moved: gene that moved its position in the hierarchy
Column 8, 11, 14 etc: Initial_level: its initial level in the WT hierarchy
Column 9, 12, 15 etc:Final_level: its final position in the rearranged hierarchy.
E. coli edge addition from Isalan et al. Columns are as follows:
Column 1: promoter_ORF_pair: the promoter and ORF fused together. This creates a new edge between the regulators of promotor and the ORF.
Column 2: Number of changes: the number of changes in the hierarchy upon addition of that new edge.
Column 3: l.s.d.: It measures the ‘least square difference’ between the mutant growth and the wild-type growth so a higher value indicates a slower cell growth.
Caution: the types of changes in this file are listed above that line. For example
appY_rpoD 0 1.58E-09
rpoE first two
appY_rpoE 1 7.23E-09
means that appY_rpoE fusion leads to 1 change which "rpoE changing from level two to level first".
Supplementary Figures and Results
Regulators involved in sensing different kinds of signals. The data was obtained from (A. Martinez-Antonio et al, Trends Microbiol 14, 22, 2006). For each category, the file lists the total number TFs involved in that category and the number of regulators that were mapped to the category followed by the TFs listed in each category. Bottom=Level 1. First = Level 2. Two = Level 3. Three = Level 4.
