This page contains supplementary material to the paper published in the Journal of Bacteriology, in which new E. coli OxyR binding sites were discovered by an information theory model. Two binding sites were discovered in the promoter of fhuF, one in the ahpC-dsbG promoter, and one inside the yfdI gene. Footprint predictions were made based on the sequence walkers.
Below are links to several parts of the OxyR project. Included are the original OxyR model (Model 1) and the updated model after two rounds of searching and subsequent footprinting (Model 3). The top twenty sites in the E. coli genome, found with Model 1, are displayed as Lister maps with the genes and footprints marked.
Model 1, the original model with 9 sites.
Model 3, the updated model with 16 sites.
Genome Scan Results for both Model 1 and Model 3.
Top 20 Sites from Model 1 Scan
Comparison of Model 1 and Model 3, an image that flickers between the two sequence logos, as well as a graph of the change in Ri's of the sequences comprising both of the models.
