Objective: Characterized catechol degradation by xylE enzyme

Method: Measured absorbance of catechol (275nm) and 2-hydroxymuconate semialdehyde (380nm).

  • Protocol:
  • 1) Grow cells in M9 minimal medium
  • 2) Take 1/10 dilution of cells
  • 3) Introduce 1µL of 0.05M catechol solution into the cell dilution. (Final concentration of 50&microM;).
  • 4) Quench the reaction with 5A% w/v trichloroacetate at certain time points. (0,15sec, 30sec, 45sec, 60sec, 2min).
  • 5) Spin down cells.
  • 6) Measure absorbance of supernatant.
