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
