Fig. 4From: OsnR is an autoregulatory negative transcription factor controlling redox-dependent stress responses in Corynebacterium glutamicumDNA binding of the purified His6-OsnR protein to the promoter regions of the putative target genes. The promoter and ORF regions are indicated with bars. Lanes 1 and 4 contained no protein, and lanes 2, 3, and 5 contained 0.6, 1.2, and 1.2 μg His6-OsnR, respectivelyBack to article page
