Interpro abstract (IPR015341):

This entry represents a domain found in members of the glycosyl hydrolases families 38. This domain is found in the central region that adopts a structure consisting of three alpha helices, in an immunoglobulin/albumin-binding domain-like fold. The domain is predominantly found in the enzyme alpha-mannosidase [(PUBMED:12634058)].

Glycoside hydrolase family 38 comprises enzymes with only one known activity; alpha-mannosidase (EC 3.2.1.24) (EC 3.2.1.114).

Lysosomal alpha-mannosidase is necessary for the catabolism of N-linked carbohydrates released during glycoprotein turnover. The enzyme catalyses the hydrolysis of terminal, non-reducing alpha-D-mannose residues in alpha-D-mannosides, and can cleave all known types of alpha-mannosidic linkages. Defects in the gene cause lysosomal alpha-mannosidosis (AM), a lysosomal storage disease characterised by the accumulation of unbranched oligo-saccharide chains.
