Figure 4From: The rgg 0182 gene encodes a transcriptional regulator required for the full Streptococcus thermophilusLMG18311 thermal adaptationAnalysis of the Rgg 0182 binding to DNA. Electrophoretic mobility shift assay (EMSA) of the promoter regions of the two target genes (shp 0182 and pep 0182 ) of Rgg0182 in the absence or in the presence of the purified His6-Rgg0182 protein. DNA probes labelled with biotin (0.1 pmol each) were incubated with 2 pmol of Rgg0182. The P ldh probe is an ldh promoter fragment used as a negative control.Back to article page
