FIGURE 2.

Formation of acyl-ACP·FabR·DNA and acyl-ACP·FadR·FabR·DNA complexes. A, electrophoretic mobility gel shifts were performed using the reagents listed above each lane to illustrate the supershift of the acyl-ACP-dependent FabR DNA gel shift in the presence of anti-ACP IgG. B, FabR and FadR simultaneously bind to the fabB promoter. Electrophoretic mobility gel shifts were performed using the reagents listed above each lane in the presence of FabR, FabR, or both transcription factors.
