Description
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. α-Mannosidase has been shown to inhibit the proliferation of B-lymphocytes. α-Mannosidase from Canavalia ensiformis is a tretamer composed of two subunits that each contain two components at 44 and 66 kDa.

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