Fig. 2.
Effect of ROS and RNS on the ability of SsrBc to bind to its ssrA cognate promoter. Effect of increasing concentrations of authentic H2O2, ONOO−, (A) or NO (B) on the binding of SsrBc to ssrA DNA. (C) Effects of NO autooxidation products on the binding of SsrBc to the ssrA promoter. The blot shows the binding of SsrBc with ssrA in untreated (U), control (C), or NO-treated samples in the presence or absence of O2. Representative data from two independent experiments are shown.
