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:0016787
|
hydrolase activity
|
Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. |
|
GO:0004553
|
hydrolase activity, hydrolyzing O-glycosyl compounds
|
Catalysis of the hydrolysis of any O-glycosyl bond. |
|
GO:0016798
|
hydrolase activity, acting on glycosyl bonds
|
Catalysis of the hydrolysis of any glycosyl bond. |
|
GO:0015925
|
galactosidase activity
|
Catalysis of the hydrolysis of galactosyl compounds, substances containing a group derived from a cyclic form of galactose or a galactose derivative. |
|
GO:0004565
|
beta-galactosidase activity
|
Catalysis of the hydrolysis of terminal, non-reducing beta-D-galactose residues in beta-D-galactosides. |
