Xanthomonas campestris pv. campestris |
Organism | Comment | Expression |
---|---|---|
Xanthomonas campestris pv. campestris | the levels of katG transcripts are markedly increased in cells treated with a superoxide generator, menadione (0.1 mM), and to a lesser extent in those treated with organic hydroperoxides (0.1 mM tert-butyl hydroperoxide or cumene hydroperoxide) or H2O2 (0.1 mM). OxyR binds in the vicinity of the katG promoter and regulates its expression | up |

---|---|---|
malfunction | a knockout mutation in katG that causes loss of catalase-peroxidase activity correlates with increased susceptibility to H2O2 and a superoxide generator and is avirulent in a plant model system. The katG mutant shows a 10fold increase in resistance to tert-butyl hydroperoxide compared with the wild type strain | Xanthomonas campestris pv. campestris |
physiological function | KatG is required for virulence of Xanthomonas campestris pv. campestris in a Chinese radish host plant by providing protection against low levels of H2O2 | Xanthomonas campestris pv. campestris |
