Specific oxidation regulates cellular functions

For a long time, hydrogen peroxide has been considered as a dangerous metabolite that can damage cells through oxidation. This, however, is not its only role in the cell. Scientists from the German Cancer Research Center have now discovered how it also transmits specific signals: Enzymes called peroxiredoxins catch the free hydrogen peroxide molecules and use them to specifically oxidize other proteins. Hydrogen peroxide thus regulates, for example, the activity of an inflammation-promoting transcription factor and hence controls important cellular functions. —> Read More Here
