Research Abstract |
Thermolysin (TLN) is a thermostable neutral metalloproteinase produced in the culture broth of Bacillus thermoproteolyticus. It is widely used for the peptide bond formation through reverse reaction of hydrolysis. In this study, for the expansion of the use of TLN in food industry, we increased the activity and stability of TLN and altered its substrate specificity using protein engineering and reaction control technology.
