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:0016757 transferase activity, transferring glycosyl groups Catalysis of the transfer of a glycosyl group from one compound (donor) to another (acceptor).
GO:0004373 glycogen (starch) synthase activity Catalysis of the reaction: UDP-glucose + (1,4)-alpha-D-glucosyl(n) = UDP + (1,4)-alpha-D-glucosyl(n+1).
GO:0016758 transferase activity, transferring hexosyl groups Catalysis of the transfer of a hexosyl group from one compound (donor) to another (acceptor).
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:0003674 molecular_function Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions.
GO:0008194 UDP-glycosyltransferase activity Catalysis of the transfer of a glycosyl group from a UDP-sugar to a small hydrophobic molecule.
GO:0035251 UDP-glucosyltransferase activity Catalysis of the transfer of a glucosyl group from UDP-glucose to an acceptor molecule.
GO:0046527 glucosyltransferase activity Catalysis of the transfer of a glucosyl group to an acceptor molecule, typically another carbohydrate or a lipid.
