The founding member of the GH95 family of glycosyl hydrolases is alpha-1,2-fucosidase that catalyses the hydrolysis of an alpha-1,2-linked fucose. A member of this family, FucOB from A. muciniphila was shown to hydrolyse all three types of H antigen structures to obtain the afucosylated Bombay phenotype [6]. Members of this family are multidomain proteins and contain a central catalytic domain with an (alpha/alpha)6 helical barrel topology, represented by this entry.	Domain

This domain is found in Alpha-fucosidase from Bifidobacterium bifidum (AfcA) and in other members of the glycoside hydrolase family 95 from bacteria and plants. AfcA hydrolyses the glycosidic linkage of Fuc1-2Gal via an inverting mechanism. This entry represents the C-terminal beta domain present within the catalytic region of this protein. The domain forms a two- layered jelly roll fold. Its specific function remains unknown [1,2].	Domain
A, B	PF14498	Glycosyl hydrolase family 65, N-terminal domain (Glyco_hyd_65N_2)	Glycosyl hydrolase family 65, N-terminal domain	This domain represents a domain found to the N-terminus of the glycosyl hydrolase 65 family catalytic domain.	Domain
