micF RNA in ompB mutants of Escherichia coli: different pathways regulate micF RNA levels in response to osmolarity and temperature change.

Abstract excerpt

The repressor RNA, micF RNA, is regulated by temperature, osmolarity, and other stress conditions during growth of Escherichia coli. Northern (RNA) blot analyses showed that levels of micF RNA differ widely in various ompB mutant strains when cells are grown at 24 degrees C in LB broth. For example, relative to the parental strain MC4100, the ompR101 mutant strain (which contains no functional OmpR) had about a...
