Transcriptional analysis of the Yersinia pestis pH 6 antigen gene.
نویسندگان
چکیده
The pH 6 antigen of Yersinia pestis is a virulence protein whose gene, psaA, is positively regulated at the transcriptional level by low pH, mammalian temperature, and an upstream locus, psaE. Low pH appears to be required for initial psaA transcription, although increased temperature is necessary for full expression of the gene. In addition, psaA is monocistronic and its transcript has a relatively long 5' nontranslated region.

The Yersinia pestis pH 6 antigen was expressed by, and purified from, Escherichia coli containing cloned psa genes. By an enzyme-linked immunosorbence-based assay, purified pH 6 antigen bound to gangliotetraosylceramide (GM1A), gangliotriaosylceramide (GM2A), and lactosylceramide (LC) (designations follow the nomenclature of L. Svennerholm [J. Neurochem. 10:613-623, 1963]). Binding to GM1A, GM2...
متن کاملRole of the PhoP–PhoQ gene regulatory system in adaptation of Yersinia pestis to environmental stress in the flea digestive tract
The Yersinia pestis PhoPQ gene regulatory system is induced during infection of the flea digestive tract and is required to produce adherent biofilm in the foregut, which greatly enhances bacterial transmission during a flea bite. To understand the in vivo context of PhoPQ induction and to determine PhoP-regulated targets in the flea, we undertook whole-genome comparative transcriptional profil...
متن کاملMolecular characterization of KatY (antigen 5), a thermoregulated chromosomally encoded catalase-peroxidase of Yersinia pestis.
The first temperature-dependent proteins (expressed at 37 degrees C, but not 26 degrees C) to be identified in Yersinia pestis were antigens 3 (fraction 1), 4 (pH 6 antigen), and 5 (hereafter termed KatY). Antigens 3 and 4 are now established virulence factors, whereas little is known about KatY, except that it is encoded chromosomally, produced in abundance, possesses modest catalase activity,...
متن کاملSimple and Rapid Detection of Yersinia Pestis and Francisella Tularensis using Multiplex-PCR
Background: Yersinia pestis and Francisella tularensis cause plague and tularemia, which are known as diseases of the newborn and elderly, respectively. Immunological and culture-based detection methods of these bacteria are time-consuming, costly, complicated and require advanced equipment. We aimed to design and synthesize a gene structure as positive control for molecular detection of these ...
متن کاملThe molecular detection of the causative agent of plague on the basis of the pla gene
Yersinia pestis, a gram-negative rod belonging to the Enterobacteriaceae family, is the causative agent of plague. Classical methods of detecting the organisms are time-consuming, expensive and dangerous. The aim of the study was to design a Real-time PCR assay on the basis of the pla gene of Yersinia pestis. In this research the Real- time PCR test was optimized by using special primers for ta...
