title: opdA, a Salmonella enterica serovar Typhimurium gene encoding a protease, is part of an operon regulated by heat shock.
abstract: The opdA (prlC) gene of Salmonella enterica serovar Typhimurium and Escherichia coli encodes the metalloprotease oligopeptidase A (OpdA). We report that opdA is cotranscribed with a downstream open reading frame, yhiQ. Transcription of this operon is induced after a temperature shift (30 to 42 degrees C), and this induction depends on the heat shock sigma factor encoded by the rpoH (htpR) gene.
