Fig 2. The C23O activities expressed by the promoter transcription fusion constructs of pSmeYxylE, pSmeDxylE, and pSmeYxylE in wild-type KJ and its derived mutants.
The overnight-cultured bacteria assayed were inoculated into fresh LB with an initial OD450nm of 0.15, cultured for 5 h, and the C23O activities were determined. The data represent means of three repetitions. Error bars indicate the standard deviation for three triplicate samples. *, p≤0.05 significance calculated by a Student’s t-test.
