Figure 9. — Surface Plasmon Resonance (SPR) analyses of binding of PvrA to the fadD1 promoter fragment. The PvrA or PvrA(R136A) protein at the indicated concentrations were injected over the immobilized DNA fragment of the fadD1 promoter region (30 bp). (A, B) The binding affinities of PvrA to the DNA probe in the absence (A) or presence (B) of palmitoyl-coenzyme A. (C, D) The binding affinities of PvrA(R136A) to the DNA probe in the absence (C) or presence (D) of palmitoyl-coenzyme A. k_a, association rate constant; k_d, dissociation rate constant; K_D, equilibrium dissociation constant. The concentrations of the proteins and values of k_a, k_d and K_D are indicated in the inset to the figures.
