We have identified a new heat shock gene, designated htpY, located 700 bp upstream of the dnaK dnaJ operon. We cloned it and showed that it is transcribed clockwise vis-à-vis the Escherichia coli genetic map, in the same direction as the dnaK dnaJ operon. The htpY gene encodes a 21,193-Da polypeptide. Promoter mapping experiments and Northern (RNA) analysis showed that the htpY gene belongs to the classical heat shock gene family, because the transcription from its major promoter is under the… CONTINUE READING
