Positive autoregulation of vipR expression in ViaB region-encoded Vi antigen of Salmonella typhi.

Journal of bacteriology - 1 Mar 1996

Hashimoto Y, Khan A Q, Ezaki T

Abstract excerpt

vipR was the first gene in the ViaB region found to be involved in production of the Vi capsular antigen in Salmonella typhi and to be transcribed in the same direction as nine downstream genes. To investigate its function, we constructed a nonpolar vipR mutant by inserting a cat cartridge into the vipR gene on the chromosome. Inactivation of the gene decreased its transcriptional level and the levels of the...
