This is our datatabase of regulatory models for Escherichia coli. Its primary goal is to assist researchers in their daily activities, providing the means to manage the catalogue as well as advanced analysis features. Database management covers the insertion, update and removal of information at each entity level, i.e., genes, transcription factors, pathways, reactions, regulatory events and so on. While providing some means of consultation and search these options are not meant for analysis purposes. Research needs in terms of data crossover and analysis led to the construction of more sophisticated and specific reports.
