EC | 3.2.1.227 | ||
Accepted name: | N-acetyllactosaminidase | ||
Reaction: | lacto-N-neotetraose + H2O = N-acetyllactosamine + lactose | ||
Glossary: | lacto-N-neotetraose = β-D-Gal-(1→4)-β-D-GlcNAc-(1→3)-β-D-Gal-(1→4)-D-Glc N-acetyllactosamine = β-D-Gal-(1→4)-D-GlcNAc |
||
Systematic name: | oligosaccharide exo β-(1,3)-N-acetyllactosamine hydrolase (non-reducing end) | ||
Comments: | The enzyme, characterized from several bacterial species, hydrolyses the terminal N-acetyllactosamine residue (β-D-Gal-(1→4)-D-GlcNAc) from the non-reducing end of oligosaccharides with the structure β-D-Gal (1→4)-β-D-GlcNAc-(1→3)-β-D-Gal-(1→R). The enzyme also catalyses the activity of EC 3.2.1.140, lacto-N-biosidase, and is not active on oligosaccharides with a terminal GlcNAc residue. | ||
