설명

일반 설명

α−Mannosidase from Canavalia ensiformis is a tretamer composed of two subunits that each contain two components at 44 and 66 kDa.

α-Mannosidase is an exo-glycosidase and an inc metalloenzyme.

Lysosomal α-mannosidases are class II mannosidases that belong to glycoside hydrolase family 38 and play an important role in the degradation of asparagine-linked carbohydrates of glycoproteins.

애플리케이션

α-Mannosidase can be used to liberate mannose from a variety of synthetic and natural α-mannosides. It has also been used in a study to investigate the causes of neurodegeneration in mucolipidosis II ′knock-in′ mice.

α-Mannosidase from Canavalia ensiformis (Jack bean) has been used:

• for the digestion of neutral glycans.
• to remove O-glycans from recombinant β-glucosidase
• for the inhibition of renal fibroblasts proliferation

Liberates mannose from a variety of synthetic and natural α-mannosides.

생화학적/생리학적 작용

α−Mannosidase has been shown to inhibit the proliferation of B-lymphocytes.

α-Mannosidase cleaves near α1−2-, α1−3- and α1−6-linked mannose residues.

α-Mannosidase is an acid hydrolase which is located in plant vacuoles and is thought to be involved with the turnover of N-linked glycoproteins.

단위 정의
