|
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: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:0016853
|
isomerase activity
|
Catalysis of the geometric or structural changes within one molecule. Isomerase is the systematic name for any enzyme of EC class 5. |
|
GO:0016860
|
intramolecular oxidoreductase activity
|
Catalysis of an oxidation-reduction (redox) reaction in which the hydrogen donor and acceptor are the same molecule, and no oxidized product appears. |
|
GO:0016861
|
intramolecular oxidoreductase activity, interconverting aldoses and ketoses
|
Catalysis of an oxidation-reduction (redox) reaction in which the hydrogen donor and acceptor, which is an aldose or a ketose, are the same molecule, and no oxidized product appears. |
|
GO:0004476
|
mannose-6-phosphate isomerase activity
|
Catalysis of the reaction: D-mannose 6-phosphate = D-fructose 6-phosphate. |
