|
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: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:0140640
|
catalytic activity, acting on a nucleic acid
|
Catalytic activity that acts to modify a nucleic acid. |
|
GO:0140101
|
catalytic activity, acting on a tRNA
|
Catalytic activity that acts to modify a tRNA. |
|
GO:0140098
|
catalytic activity, acting on RNA
|
Catalytic activity that acts to modify RNA. |
|
GO:0016772
|
transferase activity, transferring phosphorus-containing groups
|
Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to another (acceptor). |
|
GO:0016779
|
nucleotidyltransferase activity
|
Catalysis of the transfer of a nucleotidyl group from one compound (donor) to another (acceptor). |
|
GO:0004810
|
CCA tRNA nucleotidyltransferase activity
|
Catalysis of the reaction: a tRNA precursor + ATP + 2 CTP = a tRNA with a 3' CCA end + 3 diphosphate. |
|
GO:0070567
|
cytidylyltransferase activity
|
Catalysis of the transfer of a cytidylyl group to an acceptor. |
