The X8 domain [2] domain contains at least 6 conserved cysteine residues that presumably form three disulphide bridges. The domain is found in an Olive pollen allergen [1] as well as at the C-terminus of several families of glycosyl hydrolases [2]. This domain may be involved in carbohydrate binding. This domain is characteristic of GPI-anchored domains [4,5].	Domain
A	PF03198	Glucanosyltransferase (Glyco_hydro_72)	Glucanosyltransferase	This is a family of glycosylphosphatidylinositol-anchored beta(1-3)glucanosyltransferases. The active site residues in the Aspergillus fumigatus example Swiss:B0XT72 are the two glutamate residues at 160 and 261 [3].	Domain
