Fig. 5From: The dimerization interface in VraR is essential for induction of the cell wall stress response in Staphylococcus aureus: a potential druggable targetDNase I footprinting experiment. The top strand of PvraSR was labelled with 32P at the 5′-end, and incubated with VraR, VraR-P, VraMet13Ala (M13A), and VraRM13A subjected to phosphorylation with acetyl phosphate. The sample were each protein was absent from the reaction mixture is denoted by CBack to article page
