CzcR represses the expression of katA and katB during Zn excess. A and B Relative expression of the katA (A) and katB (B) genes in the WT and ΔczcR strains when they were cultured with or without Zn treatment. C and D Activities of PkatA-lux (C) and PkatB-lux (D) were measured in the WT and ΔczcR strains when they were cultured with or without Zn treatment. Statistical significance was calculated based on two-way analysis of variance (ANOVA) (n.s., not significant; **, P < 0.01; ***, P < 0.001)
