Steady-state behavior of receptor-less E. coli BT3388 cells expressing WT Aer-2 or vector alone, at decremental O2 concentrations between 20.9% and 1%. WT Aer-2 (pLH1) and the vector control (pProEX) were induced with 200 µM IPTG. Error bars represent the standard deviation from multiple titration experiments.
