biological_process
|
A biological process is the execution of a genetically-encoded biological module or program. It consists of all the steps required to achieve the specific biological objective of the module. A biological process is accomplished by a particular set of molecular functions carried out by specific gene products (or macromolecular complexes), often in a highly regulated manner and in a particular temporal sequence. |

GO:0003674
|
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. |

|
biological regulation
|
Any process that modulates a measurable attribute of any biological process, quality or function. |
|
GO:0050790
|
regulation of catalytic activity
|
Any process that modulates the activity of an enzyme. |
|
GO:0065009
|
regulation of molecular function
|
Any process that modulates the frequency, rate or extent of a molecular function, an elemental biological activity occurring at the molecular level, such as catalysis or binding. |
|
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:0016836
|
hydro-lyase activity
|
Catalysis of the cleavage of a carbon-oxygen bond by elimination of water. |
|
GO:0016835
|
carbon-oxygen lyase activity
|
Catalysis of the breakage of a carbon-oxygen bond. |
|
GO:0003994
|
aconitate hydratase activity
|
Catalysis of the reaction: citrate = isocitrate. The reaction occurs in two steps: (1) citrate = cis-aconitate + H2O, (2) cis-aconitate + H2O = isocitrate. This reaction is the interconversion of citrate and isocitrate via the labile, enzyme-bound intermediate cis-aconitate. Water is removed from one part of the citrate molecule and added back to a different atom to form isocitrate. |
|
GO:0043085
|
positive regulation of catalytic activity
|
Any process that activates or increases the activity of an enzyme. |
|
GO:0044093
|
positive regulation of molecular function
|
Any process that activates or increases the rate or extent of a molecular function, an elemental biological activity occurring at the molecular level, such as catalysis or binding. |
|
GO:0051349
|
positive regulation of lyase activity
|
Any process that activates or increases the frequency, rate or extent of lyase activity, the 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. |
|
GO:1904234
|
positive regulation of aconitate hydratase activity
|
Any process that activates or increases the frequency, rate or extent of aconitate hydratase activity. |
