Regulatory analysis of the Nitrosomonas europaea grpE-dnaK-dnaJ operon.
The complete nucleotide sequences of the Nitrosomonas europaea grpE and dnaJ genes were determined. Transcriptional analysis showed that grpE was transcribed as polycistronic transcripts with the dnaK and dnaJ from a sigma(32)-dependent heat-inducible promoter located upstream of grpE. This promoter had significantly less activity than one located upstream of dnaK.
