In the pathogenic bacterium Chlamydia trachomatis , a transcriptional repressor, HrcA, regulates the major heat shock operons, dnaK and groE . Cellular stress causes a transient increase in transcription of these heat shock operons through relief of

pSM19035-encoded omega protein forms a dimer (omega2) that binds to a set of 7-bp repeats with sequence 5'-NATCACN-3'. Upon binding to its cognate sites, omega2 regulates transcription of genes required for copy number control and stable inheritance
