Competition between fusion proteins and PduP for MCP binding. (A) Increasing IPTG concentrations (0, 0.01, 0.1, and 1 mM) were used to increase production of PduP1–18-GFP by S. enterica/pLac22-PduP1–18-eGFP. MCPs were purified, and Western blots were used to detect GFP and PduP. (B) Amount of PduP and eGFP associated with MCPs purified from S. enterica/pLac22-PduP1–18-eGFP grown with different IPTG concentrations based on PduP enzyme activity and relative fluorescence.
