CC   -!- FUNCTION: Involved in the degradation of chitin. ChbG is essential for
CC       growth on the acetylated chitooligosaccharides chitobiose and
CC       chitotriose but is dispensable for growth on cellobiose and chitosan
CC       dimer, the deacetylated form of chitobiose. Deacetylation of
CC       chitobiose-6-P and chitotriose-6-P is necessary for both the activation
CC       of the chb promoter by the regulatory protein ChbR and the hydrolysis
CC       of phosphorylated beta-glucosides by the phospho-beta-glucosidase ChbF.
CC       Catalyzes the removal of only one acetyl group from chitobiose-6-P to
CC       yield monoacetylchitobiose-6-P, the inducer of ChbR and the substrate
CC       of ChbF.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=H2O + N,N'-diacetylchitobiose = acetate + N-acetyl-beta-D-
CC         glucosaminyl-(1->4)-D-glucosamine; Xref=Rhea:RHEA:27469,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:28681, ChEBI:CHEBI:30089,
CC         ChEBI:CHEBI:59910; EC=3.5.1.105;
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=diacetylchitobiose-6'-phosphate + H2O = acetate + N'-
CC         monoacetylchitobiose-6'-phosphate; Xref=Rhea:RHEA:35083,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:30089, ChEBI:CHEBI:64883,
CC         ChEBI:CHEBI:71315;
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC   -!- PATHWAY: Glycan degradation; chitin degradation.
CC   -!- SUBUNIT: Homodimer.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- SIMILARITY: Belongs to the YdjC deacetylase family. ChbG subfamily.

CC   -!- FUNCTION: Probably catalyzes the deacetylation of acetylated
CC       carbohydrates an important step in the degradation of oligosaccharides.
