Effect of pH and temperature on the activities of CadA and its mutants. a Relative activities of wild-type CadA and its mutants at different pH. All the relative activities were calculated based on the activity of the wild-type CadA at pH 5.5. b Relative activities of wild-type CadA and its mutants at different temperatures. All the relative activities were calculated based on the activity of the wild-type CadA at 50 ºC. The error bars represent standard deviations calculated from triplicate experiments, and statistical significance of the different relative cadaverine yield in comparison with the wild type was evaluated using Student’s t test (*, P \(<\) 0.05, **, P \(<\) 0.01)
