Clostridium perfringens toxin production is often regulated by the Agr-like quorum sensing (QS) system signaling the VirS/VirR two-component regulatory system (TCRS), which consists of the VirS membrane sensor histidine kinase and the VirR response regulator. VirS/VirR is known to directly control expression of some genes by binding to a DNA binding motif consisting of two VirR boxes located within 500?bp of the target gene start codon. Alternatively, the VirS/VirR system can indirectly regulate production levels of other proteins by increasing expression of a small regulatory RNA, VR-RNA. Previous studies demonstrated that C. perfringens beta-toxin (CPB) production by C. perfringens type B and C strains is positively regulated by both the Agr-like QS and the VirS/VirR TCRS, but the mechanism has been unclear. The current study first inactivated the gene encoding VR-RNA to show that VirS/VirR regulation of expression does not involve VR-RNA. Subsequently, bioinformatic analyses identified a potential VirR binding motif, along with a predicted strong promoter, ～1.4?kb upstream of the open reading frame (ORF). Two insertion sequences were present between this VirR binding motif/promoter region and the ORF. PCR screening of a collection of strains carrying showed that the presence and sequence of this VirR binding motif/promoter is highly conserved among CPB-producing strains. Reverse transcription-PCR (RT-PCR) and a GusA reporter assay showed this VirR binding motif is important for regulating CPB production. These findings indicate that VirS/VirR directly regulates expression via VirS binding to a VirR binding motif located unusually distant from the start codon. Clostridium perfringens beta-toxin (CPB) is only produced by type B and C strains. Production of CPB is essential for the pathogenesis of type C-associated infections, which include hemorrhagic necrotizing enteritis and enterotoxemia in both humans and animals. In addition, CPB can synergize with other toxins during C. perfringens gastrointestinal diseases. CPB toxin production is cooperatively regulated by the Agr-like quorum sensing (QS) system and the VirS/VirR two-component regulatory system. This study now reports that the VirS/VirR regulatory cascade directly controls expression of the gene via a process involving a VirR box binding motif located unusually far (～1.4?kb) upstream of the ORF. This study provides a better understanding of the regulatory mechanisms for CPB production by the VirS/VirR regulatory cascade.
