General Information

General Information	Comment	Organism
malfunction	DELTAahpCD strain is notably more sensitive than its parent strain to hydrogen peroxide (H2O2) but not to organic peroxides (tertbutyl hydroperoxide and cumene hydroperoxide), in the early log phase. The catalase activity of the DELTAahpCD strain is affected at a relatively low level of H2O2 stress. The DELTAahpCD strain induces a reduced number of stem nodules in Sesbania rostrata with lowering of nitrogenase activity	Azorhizobium caulinodans
physiological function	AhpCD is required for resistance to low concentrations of H2O2 in the free-living stage and during symbiosis with Sesbania rostrata. AhpCD contributes to H2O2 resistance at the early log phase of Azorhizobium caulinodans growth. ahpCD is required for stem nodulation but not root nodulation in Sesbania rostrata	Azorhizobium caulinodans
physiological function	the enzyme is important for H2O2 detoxification in vitro and also critical for symbiosis of Azorhizobium caulinodans with Sesbania rostrate. The enzyme is required for stem nodulation and nitrogenase activity	Azorhizobium caulinodans
