Catalysis of the beta-elimination of the 5' deoxyribose-5-phosphate at an abasic site in DNA where a DNA-(apurinic or apyrimidinic site) lyase has already cleaved the C-O-P bond 3' to the apurinic or apyrimidinic site. Catalysis of the cleavage of the C-O-P bond 3' to the apurinic or apyrimidinic site in DNA by a beta-elimination reaction, leaving a 3'-terminal unsaturated sugar and a product with a terminal 5'-phosphate. Catalysis of the reaction: 5-enolpyruvoyl-6-hydroxy-2-succinylcyclohex-3-ene-1-carboxylate = (1R,6R)-6-hydroxy-2-succinylcyclohexa-2,4-diene-1-carboxylate + pyruvate. Catalysis of the breakage of a carbon-oxygen bond. Catalysis of the cleavage of a carbon-oxygen bond by elimination of water. Catalysis of the cleavage of a carbon-oxygen bond by the elimination of an alcohol from a polysaccharide. Catalysis of the cleavage of a carbon-oxygen bond by elimination of a phosphate. Catalysis of the reaction: O2 + 2 carboxymethyloxysuccinate = 2 glycolate + 2 fumarate. Catalysis of the reaction: O3-acetyl-L-serine + H2S = L-cysteine + acetate. Catalysis of the reaction: O-acetyl-L-homoserine + H2S = homocysteine + acetate. 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. 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.
