Illustration of the transcriptional regulator protein BrxR from the bacterium Escherichia fergusonii. This protein regulates the bacteriophage exclusion (BREX) system that some bacteria use to defend themselves against bacteriophages (viruses that infect bacteria). Activation of the system by BrxR leads to the degradation of phage nucleic acid. | |
