[CHEBI:33709, GOC:curators, ISBN:0198506732] EOG8MGVPB GO:0016829 26/110 lyase activity molecular_function "Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring." [EC:4.-.-.-, ISBN:0198547684] EOG8MGVPB GO:0004793 4/110 threonine aldolase activity molecular_function "Catalysis of the reaction: L-threonine = glycine + acetaldehyde." [EC:4.1.2.5] EOG8MGVPB GO:0003824 3/110 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."
