Miscellaneousi

Miscellaneous

The enzyme is inactivated by reaction of carbodiimide reagents with Asp-375. Since the antibiotic 1-deoxymannojirimycin (DMM) acts as a competitive inhibitor, and it blocks the reaction with carbodiimides, Asp-375 is established as an active site. High activity in presence of EDTA.
