|
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:0004519
|
endonuclease activity
|
Catalysis of the hydrolysis of ester linkages within nucleic acids by creating internal breaks. |
|
GO:0004518
|
nuclease activity
|
Catalysis of the hydrolysis of ester linkages within nucleic acids. |
|
GO:0140640
|
catalytic activity, acting on a nucleic acid
|
Catalytic activity that acts to modify a nucleic acid. |
|
GO:0016787
|
hydrolase activity
|
Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. |
|
GO:0016788
|
hydrolase activity, acting on ester bonds
|
Catalysis of the hydrolysis of any ester bond. |
|
GO:0140098
|
catalytic activity, acting on RNA
|
Catalytic activity that acts to modify RNA. |
|
GO:0004521
|
RNA endonuclease activity
|
Catalysis of the hydrolysis of ester linkages within ribonucleic acid by creating internal breaks. |
|
GO:0004540
|
RNA nuclease activity
|
Catalysis of the hydrolysis of phosphodiester bonds in chains of RNA. |
|
GO:0016892
|
RNA endonuclease activity, producing 3'-phosphomonoesters
|
Catalysis of the hydrolysis of ester linkages within ribonucleic acids by creating internal breaks to yield 3'-phosphomonoesters. |
|
GO:0016829
|
lyase activity
|
Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring. |
|
GO:0016849
|
phosphorus-oxygen lyase activity
|
Catalysis of the cleavage of a phosphorus-oxygen bond by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. |
|
GO:0033897
|
ribonuclease T2 activity
|
Catalysis of the reaction: a ribonucleotidyl-ribonucleotide-RNA + H2O = a 3'-end 3'-phospho-ribonucleotide-RNA + a 5'-end dephospho-ribonucleoside-RNA + H+. This reaction is a two-stage endonucleolytic cleavage to nucleoside 3'-phosphates and 3'-phosphooligonucleotides with 2',3'-cyclic phosphate intermediates. |
