Expression

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

General Information

General Information	Comment	Organism
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
