RegulonDB is a database on mechanisms of transcription regulation and operon organization in Escherichia coli K-12. The current version has considerably increased in number of regulatory elements such as promoters, binding sites, and terminators. The complete repertoire of known and predicted DNA-binding transcriptional regulators can be considered included in this version. The database now distinguishes different allosteric conformations of regulatory proteins indicating the one active in binding and regulating the different promoters. A new set of operon predictions is incorporated. The relational design has been modified accordingly. Furthermore, a major improvement is a graphical display enabling browsing of the database with a Java-based interactive interphase with three zoom-levels connected to properties of each chromosomal element. The purpose of these modifications is to make of RegulonDB a useful tool and control set for transcriptome experiments.
