So-called ζ^32 factor of Escherichia coli is embedded into the RNA-thermosensor in the λ cIII gene and plays an important role in the regulation of bacterial response to hightened temperatures. Expression of heat/cold-shock genes and some virulence genes in response to temperature changes is coordinated by the genome. There are some known RNA-thermosensors with different structures that provide a functional control of the diversity of cellular processes.

A common feature is functionally important and it is elimination that makes the RNA-thermosensor insensitive to high temperatures. In this paper we describe molecular sequences (RNA-thermosensor) whose chemical compounds influence on the homeostatic temperature regulation, namely, on the corresponding enzymes.
