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:0140640
|
catalytic activity, acting on a nucleic acid
|
Catalytic activity that acts to modify a nucleic acid. |
|
GO:0140097
|
catalytic activity, acting on DNA
|
Catalytic activity that acts to modify DNA. |
|
GO:0016874
|
ligase activity
|
Catalysis of the joining of two molecules, or two groups within a single molecule, using the energy from the hydrolysis of ATP, a similar triphosphate, or a pH gradient. |
|
GO:0003909
|
DNA ligase activity
|
Catalysis of the formation of a phosphodiester bond between the 3'-hydroxyl group at the end of one DNA chain and the 5'-phosphate group at the end of another. This reaction requires an energy source such as ATP or NAD+. |
|
GO:0016886
|
ligase activity, forming phosphoric ester bonds
|
Catalysis of the joining of two molecules, or two groups within a single molecule, via a phosphoric ester bond, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate. |
|
GO:0003911
|
DNA ligase (NAD+) activity
|
Catalysis of the reaction: NAD+ + deoxyribonucleotide(n) + deoxyribonucleotide(m) = AMP + nicotinamide nucleotide + deoxyribonucleotide(n+m). |
