EMSA analysis with selected promoters.
Promoters of selected genes were mixed with rRex and the impact of the presence of Rex on mobility was visualized via SYBR Gold staining. Data presented here show that rRex specifically binds the promoters of adhE (A), frdC (B), gshR (C), tpn (D), and ldh (E), respectively, and when added at different concentrations, causes mobility shift as a result of formation of rRex-promoter complexes.
