| contents | Antiterminators are essential components of bacterial transcriptional regulation, allowing the control of gene expression in response to fluctuating environmental conditions. Among them, RNA-binding antiterminator proteins play a major role in preventing transcription termination by binding to specific RNA sequences. These RNA-binding antiterminators have been extensively studied for their role in regulating various metabolic pathways. However, their function in modulating the physiology of pathogens requires further investigation. This review focuses on RNA-binding proteins displaying CAT (Co-AntiTerminator) or ANTAR (AmiR and NasR Transcription Antitermination Regulators) domains reported in model bacteria. In particular, their structures, mechanism of action, and target genes will be described. The involvement of the antitermination mechanisms in bacterial pathogenicity is also discussed. This knowledge is crucial for understanding the regulatory mechanisms that control bacterial virulence, and opens up exciting prospects for future research, and potentially new alternative strategies to combat infectious diseases. |
