biological_process
|
A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence. |
|
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. |

|
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:0065007
|
biological regulation
|
Any process that modulates a measurable attribute of any biological process, quality or function. |
|
GO:0050790
|
regulation of catalytic activity
|
Any process that modulates the activity of an enzyme. |
|
GO:0051338
|
regulation of transferase activity
|
Any process that modulates the frequency, rate or extent of transferase activity, the 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:0065009
|
regulation of molecular function
|
Any process that modulates the frequency, rate or extent of a molecular function, an elemental biological activity occurring at the molecular level, such as catalysis or binding. |
|
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. |
|
GO:0033840
|
alpha-1,4-glucan glucosyltransferase (NDP-glucose donor) activity
|
Catalysis of the reaction: [(1->4)-alpha-D-glucosyl](n) + an NDP-alpha-D-glucose = [(1->4)-alpha-D-glucosyl](n+1) + a ribonucleoside 5'-diphosphate + H+, where NDP is ADP or UDP. |
|
GO:0004373
|
alpha-1,4-glucan glucosyltransferase (UDP-glucose donor) activity
|
Catalysis of the reaction: [(1->4)-alpha-D-glucosyl](n) + UDP-alpha-D-glucose = [(1->4)-alpha-D-glucosyl](n+1) + H+ + UDP. |
|
GO:2000465
|
regulation of glycogen (starch) synthase activity
|
Any process that modulates the frequency, rate or extent of glycogen (starch) synthase activity. |
