Figure 5From: The photosensor protein Ppr of Rhodocista centenaria is linked to the chemotaxis signalling pathwayBinding of the histidine kinase domain Pph to Rc-CheW. Purified Pph protein was immobilized on an aminosilane cuvette and increasing amounts of Rc-CheW were added. After 30 minutes of incubation the free protein was removed and the bound Rc-CheW was calculated. The corresponding Scatchard plot is shown in the inlet.Back to article page
