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: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:0008026
|
ATP-dependent helicase activity
|
Catalysis of the reaction: ATP + H2O = ADP + phosphate, to drive the unwinding of a DNA or RNA helix. |
GO:0004386
|
helicase activity
|
Catalysis of the reaction: NTP + H2O = NDP + phosphate, to drive the unwinding of a DNA or RNA helix. |
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:0050790
|
regulation of catalytic activity
|
Any process that modulates the activity of an enzyme. |
GO:0043086
|
negative regulation of catalytic activity
|
Any process that stops or reduces the activity of an enzyme. |
GO:0003724
|
RNA helicase activity
|
Catalysis of the reaction: NTP + H2O = NDP + phosphate, to drive the unwinding of a RNA helix. |
GO:0016032
|
viral process
|
A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle. |
GO:0017111
|
nucleoside-triphosphatase activity
|
Catalysis of the reaction: a nucleoside triphosphate + H2O = nucleoside diphosphate + phosphate. |
GO:0009987
|
cellular process
|
Any process that is carried out at the cellular level, but not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level. |
GO:0008186
|
RNA-dependent ATPase activity
|
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction requires the presence of RNA, and it drives another reaction. |
GO:0004004
|
ATP-dependent RNA helicase activity
|
Catalysis of the reaction: ATP + H2O = ADP + phosphate; this reaction drives the unwinding of an RNA helix. |
GO:0019048
|
modulation by virus of host morphology or physiology
|
The process in which a virus effects a change in the structure or processes of its host organism. |
GO:0032780
|
negative regulation of ATPase activity
|
Any process that stops or reduces the rate of ATP hydrolysis by an ATPase. |
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. |
GO:0065007
|
biological regulation
|
Any process that modulates a measurable attribute of any biological process, quality or function. |
GO:0050789
|
regulation of biological process
|
Any process that modulates the frequency, rate or extent of a biological process. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule. |
GO:0019222
|
regulation of metabolic process
|
Any process that modulates the frequency, rate or extent of the chemical reactions and pathways within a cell or an organism. |
GO:0065009
|
