This is a subdomain found in the C-terminal region of golgi alpha-mannosidase II present in Drosophila melanogaster. These proteins are important in glycoprotein processing and are thought to cleave mannosidic bonds through a double displacement mechanism involving a reaction intermediate.This subdomain is found at the C-terminal of Glycosyl hydrolases family 38 C-terminal domain [1].

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].	Domain
A	PF09261	Alpha mannosidase middle domain (Alpha-mann_mid)	Alpha mannosidase middle domain	Members of this family adopt a structure consisting of three alpha helices, in an immunoglobulin/albumin-binding domain-like fold. They are predominantly found in the enzyme alpha-mannosidase [1].	Domain
