With the inducing time prolonged, the amount of fusion protein increased, and the highest content amounted to 39. 14% of total protein. Different temperature (15℃, 25℃ and 37℃) could induce expression of fusion protein, and the higher inducing temperature was, the more total fusion protein and soluble fusion protein was produced. Most fusion protein was expressed in the cytoplasm and was soluble, a little of fusion protein was expressed in periplasm or expressed as inclusion bodies, and no fusion protein was found in culture. Furthermore, the results of in vitro enzymatic reaction suggested that the fusion protein could catalyze the methylation of theobromine.
