Descripción general
β-Mannosidase is a lysosomal enzyme that belongs to the glycosyl hydrolase family 2.
Aplicación
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
Acciones bioquímicas o fisiológicas
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.

Statistical modeling was applied for describing structural features of β-(1→4)-D-galactomannans. According to the model suggested theoretical ratios of limiting degrees of locust bean, tara gum and guar gum galactomannan conversions by two β-(1→4)-mannanases of different origin (Myceliophthora thermophila and Trichoderma

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
