|
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:0016787
|
hydrolase activity
|
Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
|
GO:0016887
|
ATPase activity
|
Catalysis of the reaction: ATP + H2O = ADP + phosphate + 2 H+. May or may not be coupled to another reaction. |
|
GO:0008152
|
metabolic process
|
The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances. Metabolic processes typically transform small molecules, but also include macromolecular processes such as DNA repair and replication, and protein synthesis and degradation. |
|
GO:0008094
|
DNA-dependent ATPase activity
|
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction requires the presence of single- or double-stranded DNA, and it drives another reaction. |
|
GO:0016817
|
hydrolase activity, acting on acid anhydrides
|
Catalysis of the hydrolysis of any acid anhydride. |
|
GO:0016818
|
hydrolase activity, acting on acid anhydrides, in phosphorus-containing anhydrides
|
Catalysis of the hydrolysis of any acid anhydride which contains phosphorus. |
|
GO:0016462
|
pyrophosphatase activity
|
Catalysis of the hydrolysis of a pyrophosphate bond between two phosphate groups, leaving one phosphate on each of the two fragments. |
|
GO:0042623
|
ATPase activity, coupled
|
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction directly drives some other reaction, for example ion transport across a membrane. |
|
GO:0043142
|
single-stranded DNA-dependent ATPase activity
|
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction requires the presence of single-stranded DNA, and it drives another reaction. |
|
GO:0017111
|
nucleoside-triphosphatase activity
|
Catalysis of the reaction: a nucleoside triphosphate + H2O = nucleoside diphosphate + phosphate. |
|
GO:0008150
|
biological_process
|
Any process specifically pertinent to the functioning of integrated living units: cells, tissues, organs, and organisms. A process is a collection of molecular events with a defined beginning and end. |
|
GO:0003674
|
molecular_function
|
Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. |
