Transcription of ahpC, katG, and katE genes in Escherichia coli is regulated by polyamines: polyamine-deficient mutant sensitive to H2O2-induced oxidative damage.

Biochemical and biophysical research communications - 21 Feb 2003

Jung Il Lae, Kim In Gyu

Abstract excerpt

Polyamines (putrescine and spermidine) are present in almost all living organisms and participate in numerous cellular processes. In this study, we report the protective roles of polyamines against hydrogen peroxide (H2O2)-induced oxidative stress. All of ahpC, katG, and katE genes, known to participate in the antioxidant defense mechanism against H2O2-induced stress in Escherichia coli, failed to induce in the...
