Comparative expression analysis between sigE (TTHB211) deletion mutant and wild-type of T. thermophilus HB8

ABSTRACT: We observed the expression profile of the total mRNA of sigE (TTHB211) deletion mutant of Thermus thermophilus HB8 strain grown in a rich (TT) medium at 70oC compared with that of wild type. Keywords: cell type comparison Three wild-type and mutant T. thermophilus HB8 strains were each pre-cultured at 70oC for 16 h in 3 ml of TT medium containing 0.8% polypeptone, 0.4% yeast extract, 0.2% NaCl, 0.4 mM CaCl2, and 0.4 mM MgCl2, which was adjusted to pH 7.2 with NaOH. The cells (2 ml) were inoculated into 1 liter of the same medium and then cultivated at 70oC. Cells were collected after 8 h, and then crude RNA was extracted. In order to compare mRNA expression in the sigE (TTHB211) deletion mutant with that of wild type, the expression of each mRNA at the time point was analyzed on a GeneChip as described under Sample Description Sheet of each sample in this website.

Journal of bacteriology 20070928 23

Thermus thermophilus sigma(E), an extracytoplasmic function sigma factor from the extremely thermophilic bacterium Thermus thermophilus HB8, bound to the RNA polymerase core enzyme and showed transcriptional activity. With the combination of in vitro transcription assay and GeneChip technology, we identified three promoters recognized by sigma(E). The predicted consensus promoter sequence for sigma(E) is 5'-CA(A/T)(A/C)C(A/C)-N(15)-CCGTA-3'. ...[more]
