Transcription of the mutL repair, miaA tRNA modification, hfq pleiotropic regulator, and hflA region protease genes of Escherichia coli K-12 from clustered Esigma32-specific promoters during heat shock.

Abstract excerpt

The amiB-mutL-miaA-hfq-hflX-hflK-hflC superoperon of Escherichia coli contains genes that are important for diverse cellular functions, including DNA mismatch repair (mutL), tRNA modification (miaA), pleiotropic regulation (hfq), and proteolysis (hflX-hflK-hflC). We show that this superoperon contains three E simga(32)-dependent heat shock promoters, P(mutL)HS,P(miaA)HS, and P1(hfq)HS, in addition to four E...
