Detoxification of hydrogen peroxide and expression of catalase genes in Free

Abstract

The two related facultatively photosynthetic bacteria and show different sensitivities against peroxide stress. is able to tolerate higher concentrations of HO and exhibits higher catalase activity than . The gene of and the gene of are strongly induced by HO. This induction depends on the presence of the OxyR protein, which is able to bind to the promoter regions of these genes. In addition to harbours the gene, which shows no significant response to HO but is induced in stationary phase.
