일반 설명
β-Mannosidase is a lysosomal enzyme that belongs to the glycosyl hydrolase family 2.
애플리케이션
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
생화학적/생리학적 작용
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.
