| Abstract |
The FixJ/LuxR family transcription factor CsgD is a master regulator of biofilm formation in Escherichia coli. Previously, we identified more than 10 transcription factors that participate in regulation of the csgD promoter. After genomic SELEX screening of regulation targets, an uncharacterized TetR-type transcription factor YbjK was found to be involved in regulation of the csgD promoter. In addition, a number of stress-response genes were found to be under the direct control of YbjK. Taken together, we propose to rename it to RcdA (regulator of csgD). One unique feature of RcdA is its mode of DNA binding. Gel shift, DNase-I footprinting, and atomic force microscopic (AFM) analyses indicated that RcdA is a DNA-binding protein with a high level of cooperativity, with which it covers the entire surface of probe DNA through protein-protein interaction and moreover it induces the formation of aggregates of DNA-RcdA complexes. |
