Fig. 4From: The dimerization interface in VraR is essential for induction of the cell wall stress response in Staphylococcus aureus: a potential druggable targetCoomassie blue staining of the 10% Native-PAGE of VraR and VraRM13A (M13A) phosphorylated by acetyl phosphate (AP). Briefly, VraR at the concentrations denoted in the figure was phosphorylated by 50 mM acetyl phosphate in the PB buffer for 1 h, at 37 °CBack to article page
