pubmed:abstractText |
The transposon TnphoA was used to generate fusions between phoA, the gene for alkaline phosphatase (PhoA), and genes encoding proteins that are secreted by Vibrio cholerae. One of the PhoA+ mutants isolated showed a dramatic reduction in its ability to colonize the intestines of suckling mice. This mutant no longer produced a 20.5-kDa protein (TcpA) that we show is the major subunit of a V. cholerae pilus. Amino-terminal sequence analysis of the TcpA pilus subunit showed that it shares amino acid homology with the pilins produced by several other pathogenic bacteria. The TcpA pilus was coordinately expressed with cholera toxin under various culture conditions, and this effect appeared to be dependent on the transcriptional activator encoded by the toxR gene. We conclude that the toxR gene plays a central role in the transcriptional regulation of multiple virulence genes of V. cholerae.
