EOG8XSP3R GO:0046872 13/72 metal ion binding molecular_function "Interacting selectively and non-covalently with any metal ion." [GOC:ai] EOG8XSP3R GO:0003824 12/72 catalytic activity molecular_function "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."
