The LogoMotif database

The LogoMotif database is an up-to-date comprehensive database on gene regulation in bacteria. It contains curated experimentally-validated transcription factor binding site (TFBS) profiles and preconstructed position frequency matrices (PFMs) and position weight matrices (PWMs). The matrices are pre-applied to several model organisms to detect TFBS locations and construct gene regulatory networks.
