EOG8MWBM0 GO:0046872 31/96 metal ion binding molecular_function "Interacting selectively and non-covalently with any metal ion." [GOC:ai] EOG8MWBM0 GO:0006508 28/96 proteolysis biological_process "The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds." [GOC:bf, GOC:mah] EOG8MWBM0 GO:0003824 27/96 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."
