|
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:0008152
|
metabolic process
|
The chemical reactions and pathways, including anabolism and catabolism, by which living organisms transform chemical substances.
