A CdtA-CdtC complex can block killing of HeLa cells by Haemophilus ducreyi cytolethal distending toxin.
The cytolethal distending toxin (CDT) of Haemophilus ducreyi is comprised of the CdtA, CdtB, and CdtC proteins, with the CdtB protein having demonstrated enzymatic (i.e., DNase) activity. Using a single recombinant Escherichia coli strain with two plasmids individually containing the H. ducreyi cdtA and cdtC genes, we purified a noncovalent CdtA-CdtC complex. Incubation of this CdtA-CdtC comple...
متن کاملCytolethal distending toxin demonstrates genotoxic activity in a yeast model.
Cytolethal distending toxins (CDTs) are multisubunit proteins produced by a variety of bacterial pathogens that cause enlargement, cell cycle arrest, and apoptosis in mammalian cells. While their function remains uncertain, recent studies suggest that they can act as intracellular DNases in mammalian cells. Here we establish a novel yeast model for understanding CDT-associated disease. Expressi...
متن کاملIntrons in the cytolethal distending toxin gene of Actinobacillus actinomycetemcomitans.
In eukaryotic cells, genes are interrupted by intervening sequences called introns. Introns are transcribed as part of a precursor RNA that is subsequently removed by splicing, giving rise to mature mRNA. However, introns are rarely found in bacteria. Actinobacillus actinomycetemcomitans is a periodontal pathogen implicated in aggressive forms of periodontal disease. This organism has been show...
متن کاملDynamics and assembly of the cytolethal distending toxin.
The cytolethal distending toxin (CDT) is a widespread bacterial toxin that consists of an active subunit CdtB with nuclease activity and two ricin-like lectin domains, CdtA and CdtC, that are involved in the delivery of CdtB into the host cell. The three subunits form a tripartite complex that is required to achieve the fully active holotoxin. In the present study we investigate the assembly an...
