Descrizione generale

β-Mannosidase is a lysosomal enzyme that belongs to the glycosyl hydrolase family 2.

Applicazioni

β-Mannosidase from Helix pomatia has been used:
  • in the digestion of glycans for enzymatic analysis
  • in the treatment of labeled monogalactosyl Manno-oligosaccharides
  • in non-mammalian glycosidase inhibition assays

Azioni biochim/fisiol

β-Mannosidase participates in cleaving the β(1–4)-linked mannose located at the nonreducing end of N-glycosylated proteins. It is involved in the polysaccharide degradation pathway. In humans, mutations in the gene are associated with β-mannosidosis, a lysosomal storage disease. Low levels of β-Mannosidase due to mutations also lead to nystagmus, an eye disorder associated with involuntary eye movements.

Definizione di unità

β-Mannosidase (EC 3.2.1.25) is an exoglycosidase specific for the hydrolysis of terminal β-linked mannoside in various sugar chains. cDNA corresponding to the β-mannosidase gene was cloned from Aspergillus niger, sequenced, and expressed in the yeast Pichia pastoris. The β-mannosidase gene

Glucomannan polysaccharides may be hydrolysed to lower molecular weight molecules using acids or enzymes, specifically mannanases or cellulases. Mannanases (β-mannanases) hydrolyse β-(1-4)-linked mannose residues randomly in mannans whilst cellulases (β-glucanase) hydrolyse β-(1-4)-linked glucose residues. The molecular weight of the hydrolysate
