Definition
Catalysis of the reaction: N,N'-diacetylchitobiose (GlcNac2) + H2O = acetate + 2-acetamido-4-O-(2-amino-2-deoxy-beta-D-glucopyranosyl)-2-deoxy-D-glucose (GlcN-GlcNAc). Source: GOC:mengo_curators, MetaCyc:RXN-12543, PMID:16232910, PMID:16736587, GOC:bf, PMID:15136574
Comment
In this reaction N,N'-diacetylchitobiose is deacetylated at the non-reducing residue to produce 2-acetamido-4-O-(2-amino-2-deoxy-beta-D-glucopyranosyl)-2-deoxy-D-glucose (GlcN-GlcNAc). This is in contrast to EC:3.5.1.105 in which N,N'-diacetylchitobiose is deacetylated at the reducing residue to produce 4-O-(N-acetyl-beta-D-glucosaminyl)-D-glucosamine (GlcNAc-GlcN). For the latter reaction, see GO:0036311.
