Figure 4From: Biochemical characterization of three putative ATPases from a new type IV secretion system of Aeromonas veronii plasmid pAC3249AFluorescence spectra of TNP-ATP and TNP-CTP-bound TraJ. TraJ showed similar binding affinity for ATP and CTP. No shift in the absorption maximum of the fluorescent ATP and CTP analogues was observed.Back to article page
