When tetracycline was present, tetA(C) reduced acid tolerance, suppressed rpoS expression, and increased the concentration of total soluble proteins in stationary-phase Escherichia coli. The suppression of acid tolerance was reversed by 85 mM sodium, potassium, magnesium, and calcium ions but not by 85 mM sucrose. Implications for using TetA(C) are discussed.
