Identifier	Name	Description
GO:0003674	molecular_function	A molecular process that can be carried out by the action of a single macromolecular machine, usually via direct physical interactions with other molecular entities. Function in this sense denotes an action, or activity, that a gene product (or a complex) performs.
GO:0016757	glycosyltransferase activity	Catalysis of the transfer of a glycosyl group from one compound (donor) to another (acceptor).
GO:0016758	hexosyltransferase activity	Catalysis of the transfer of a hexosyl group from one compound (donor) to another (acceptor).
GO:0003824	catalytic activity	Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
GO:0016740	transferase activity	Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
GO:0140096	catalytic activity, acting on a protein	Catalytic activity that acts to modify a protein.
GO:0008194	UDP-glycosyltransferase activity	Catalysis of the transfer of a glycosyl group from a UDP-sugar to a small hydrophobic molecule.
GO:0008378	galactosyltransferase activity	Catalysis of the transfer of a galactosyl group to an acceptor molecule, typically another carbohydrate or a lipid.
GO:0140103	catalytic activity, acting on a glycoprotein	Catalysis of a biochemical reaction in which one of the substrates is a glycoprotein.
GO:0035250	UDP-galactosyltransferase activity	Catalysis of the transfer of a galactose group from UDP-galactose to an acceptor molecule.
GO:0047220	galactosylxylosylprotein 3-beta-galactosyltransferase activity	Catalysis of the reaction: 4-beta-D-galactosyl-O-beta-D-xylosylprotein + UDP-galactose = 3-beta-D-galactosyl-4-beta-D-galactosyl-O-beta-D-xylosylprotein + UDP.
