Native Human β-N-Acetylglucosaminidase

Cat No.
NATE-0781
Description
This enzyme, sometimes called β-N-acetylhexosaminidase, is reported to liberate terminal β-linked N-acetylglucosamine and N-acetylgalactosamine from a variety of substrates. The activity of β-N-actylglucosaminidase may be determined with the chromogenic substrate p-nitrophenyl-N-acetyl-β-D-glucosaminide. β-N-actylglucosaminidase hydrolyzes the terminal nonreducing N-acetyl-D-hexosamine residues. This enzyme contains two predominant isozymes, Hex A, a heterodimer, and Hex B, a homodimer. N-acetylglucosamine, acetamide, N-2-acetamido-2-deoyglucosylamine, N-acetylnojirimycin, and N-acetyldeoxynojirmycin are known inhibitors.

Applications
β-N-acetylglucosaminidase is a lysosomal enzyme used to hydrolyze N-acetyl-β-D-glucosaminides and N-acetyl-β-Dgalactosaminides. It is used in chemoenzymatic synthesis of oligosaccharides based on their effective transglycosylation of β-GlcNAc and β-GalNAcc. It may be a useful tool to study Alzheimer’s Disease.
