Name Di-N-acetylchitobiase
Synonyms Not Available
Gene Name CTBS
Protein Type Enzyme
Biological Properties
General Function Involved in chitinase activity
Specific Function Involved in the degradation of asparagine-linked glycoproteins. Hydrolyze of N-acetyl-beta-D-glucosamine (1-4)N- acetylglucosamine chitobiose core from the reducing end of the bond, it requires prior cleavage by glycosylasparaginase
