ENZYME entry: EC 3.5.1.136

Accepted Name
N,N'-diacetylchitobiose non-reducing end deacetylase.
Alternative Name(s)
Diacetylchitobiose deacetylase.
Reaction catalysed
N,N'-diacetylchitobiose + H(2)O <=> beta-D-glucosaminyl-(1->4)-N-acetyl-D-glucosamine + acetate
Comment(s)
  • The enzyme, characterized from the archaeons Thermococcus kodakarensis and Pyrococcus horikoshii, deacetylates the non-reducing residue of N,N'-diacetylchitobiose, the end product of the archaeal chitinase, to produce beta-D-glucosaminyl-(1->4)-N-acetyl-D- glucosamine.
  • This is in contrast to EC 3.5.1.105, chitin disaccharide deacetylase, which deacetylates N,N'-diacetylchitobiose at the reducing residue to produce N-acetyl-beta-D-glucosaminyl-(1->4)-D-glucosamine.
