|
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: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. |
|
GO:0008373
|
sialyltransferase activity
|
Catalysis of the transfer of sialic acid to an acceptor molecule, typically the terminal portions of the sialylated glycolipids (gangliosides) or to the N- or O-linked sugar chains of glycoproteins. |
|
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:0071704
|
organic substance metabolic process
|
The chemical reactions and pathways involving an organic substance, any molecular entity containing carbon. |
|
GO:0043412
|
macromolecule modification
|
The covalent alteration of one or more monomeric units in a polypeptide, polynucleotide, polysaccharide, or other biological macromolecule, resulting in a change in its properties. |
|
GO:0008150
|
biological_process
|
Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end. |
|
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:0043170
|
macromolecule metabolic process
|
The chemical reactions and pathways involving macromolecules, any molecule of high relative molecular mass, the structure of which essentially comprises the multiple repetition of units derived, actually or conceptually, from molecules of low relative molecular mass. |
|
GO:0097503
|
sialylation
|
The covalent attachment of sialic acid to a substrate molecule. |
|
GO:0003835
|
beta-galactoside alpha-2,6-sialyltransferase activity
|
Catalysis of the reaction: CMP-N-acetylneuraminate + beta-D-galactosyl-(1->4)-acetyl-beta-D-glucosamine = CMP + alpha-N-acetylneuraminyl-(2->6)-beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosamine. |
