Comments (originally from EcoCyc)  demonstrated that both oxyR and ahpC gene expressions, which codify a transcriptional regulator and a product essential for the detoxification against H2O2-induced stress, respectively, were absolutely dependent on polyamines during entry into the stationary phase. These data suggest that polyamines could be directly participating in the defense mechanism against oxidative stress.
