Collections of regulogs classified by transcription factors

Each transcription factor collection organizes all reconstructed regulogs for a given set of orthologous regulators across different taxonomic groups of microorganisms. These collections represent regulons for a selected subset of transcription factors. The collections include both widespread transcription factors such as NrdR, LexA, and Zur, that are present in more than 25 diverse taxonomic groups of Bacteria, and narrowly distributed transcription factors such as Irr and PurR. The TF regulon collections are valuable for comparative and evolutionary analysis of TF binding site motifs and regulon content for orthologous transcription factors.
