EOG8DJNB3 GO:0030976 5/12 thiamine pyrophosphate binding molecular_function "Interacting selectively and non-covalently with thiamine pyrophosphate, the diphosphoric ester of thiamine. Acts as a coenzyme of several (de)carboxylases, transketolases, and alpha-oxoacid dehydrogenases." [CHEBI:45931, GOC:mlg] EOG8DJNB3 GO:0000287 5/12 magnesium ion binding molecular_function "Interacting selectively and non-covalently with magnesium (Mg) ions." [GOC:ai] EOG8DJNB3 GO:0003824 4/12 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."
