This domain is found in Lysosomal alpha-mannosidase from Bos taurus (Laman) and similar proteins from eukaryotes. This protein is necessary for the catabolism of N-linked carbohydrates released during glycoprotein turnover. Laman, which belongs to the glycoside hydrolase family 38 (GH38), is organised into four domains: the alpha-beta N-terminal Pfam:PF01074, a three-helix bundle domain Pfam:PF09261, and three mainly beta-sheet domains (covered by this entry, Pfam:PF07748 and Pfam:PF17677) [1-5].
