FIG. 7.

Transcriptional organization of the H. pylori 69A htpG gene. (A) Northern blot analysis. Cells were grown at 37°C and heat shocked by upshift to 42°C. RNA (10 μg per lane) isolated before thermal upshift (0) and at the indicated times after heat shock was separated by electrophoresis in a 1.2% gel and blotted to a nylon membrane. Hybridization was performed using an htpG-specific RNA probe. (B) Schematic representation of the htpG gene and the detected monocistronic mRNA. The putative rho-independent transcriptional terminator downstream of htpG is indicated.
