|
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:0016746
|
transferase activity, transferring acyl groups
|
Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor). |
|
GO:0016747
|
transferase activity, transferring acyl groups other than amino-acyl groups
|
Catalysis of the transfer of an acyl group, other than amino-acyl, from one compound (donor) to another (acceptor). |
|
GO:0016788
|
hydrolase activity, acting on ester bonds
|
Catalysis of the hydrolysis of any ester bond. |
|
GO:0016740
|
transferase activity
|
Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2. |
|
GO:0016790
|
thiolester hydrolase activity
|
Catalysis of the reaction: RCO-SR' + H2O = RCOOH + HSR'. This reaction is the hydrolysis of a thiolester bond, an ester formed from a carboxylic acid and a thiol (i.e., RCO-SR'), such as that found in acetyl-coenzyme A. |
|
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:0004312
|
fatty acid synthase activity
|
Catalysis of the reaction: acetyl-CoA + n malonyl-CoA + 2n NADPH + 2n H+ = long-chain fatty acid + n+1 CoA + n CO2 + 2n NADP+. |
|
GO:0016297
|
acyl-[acyl-carrier-protein] hydrolase activity
|
Catalysis of the reaction: acyl-[acyl-carrier protein] + H2O = [acyl-carrier protein] + a fatty acid. |
