Description

The protein IrrE originates from Deinococcus radiodurans, where it confers resistance to radiation. When transformed into E. Coli however, it protected against salt, oxidative and thermal shock. IrrE appears to function as a global regulator of stress factor genes. So far it has been demonstrated to upregulate transcription of recA and pprA – genes which encode Recombinase A and Radiation Inducible Protein. With respect to salt tolerance, IrrE upregulates the production of several stress responsive proteins, protein kinases, metabolic proteins, and detoxification proteins. It also downregulates glycerol degradation. With this global regulatory effect, E. Coli becomes more salt tolerant.
