molecular function
	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:0016757		transferase activity, transferring glycosyl groups		Catalysis of the transfer of a glycosyl group from one compound (donor) to another (acceptor).
