Identifier Name Description
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.
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:0000016 lactase activity Catalysis of the reaction: lactose + H2O = D-glucose + D-galactose.
GO:0016798 hydrolase activity, acting on glycosyl bonds Catalysis of the hydrolysis of any glycosyl bond.
