PRODORIC2: The Bacterial Gene Regulation Database in 2018

Bacteria adapt to changes in their environment via differential gene expression mediated by DNA binding transcriptional regulators. The PRODORIC2 database hosts one of the largest collections of DNA binding sites for prokaryotic transcription factors. It is the result of the thoroughly redesigned PRODORIC database. PRODORIC2 is more intuitive and user-friendly. Besides significant technical improvements, the new update offers more than 1000 new transcription factor binding sites and 110 new position weight matrices for genome-wide pattern searches with the Virtual Footprint tool. Moreover, binding sites deduced from high-throughput experiments were included. Data for 6 new bacterial species including bacteria of the Rhodobacteraceae family were added. Finally, a comprehensive collection of sigma- and transcription factor data for the nosocomial pathogen Clostridium difficile is now part of the database. PRODORIC2 is publicly available at

A matrix report page for the transcription factor FnrL from D. shibae. Links providing additional information about the reference strain and the transcription factor are depicted at the top of the page. The position weight matrix is shown in tabulated form and the corresponding binding sites (here truncated) are shown below the matrix as they appear in the original manuscript. Their genomic coordinates, strand orientation and the original citation(s) are provided as well. The accession numbers of the TFBSs are hyperlinked to the NCBI genome browser.
