Asymmetric Unit(hide GO term definitions)

Chain A,B (Q8KNF2_MICEC | Q8KNF2)

molecular function
	GO:0016758	transferase activity, transferring hexosyl groups	Catalysis of the transfer of a hexosyl group from one compound (donor) to another (acceptor).
biological process
	GO:0005975	carbohydrate metabolic process	The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule.
	GO:0030259	lipid glycosylation	Covalent attachment of a glycosyl residue to a lipid molecule.
	GO:0008152	metabolic process	The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation.
