Catalysis of the cleavage of a C-C bond in a molecule containing a hydroxyl group and a carbonyl group to form two smaller molecules, each being an aldehyde or a ketone. Catalysis of the cleavage of a C-C bond by other means than by hydrolysis or oxidation, of a 3-hydroxy acid. Catalysis of the reaction: A C(n) aldehyde = C(n-1) alkane + CO. Catalysis of the reaction: L-tryptophan + H2O = indole + pyruvate + NH3. 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. Catalysis of the repair of a photoproduct resulting from ultraviolet irradiation of two adjacent pyrimidine residues in DNA. Catalysis of the reaction: fumarate + n-hexane = (1-methylpentyl)succinate. Catalysis of the reaction: L-tyrosine + H2O = phenol + pyruvate + NH3. Catalysis of the nonhydrolytic addition or removal of a carboxyl group to or from a compound. Catalysis of the cleavage of C-C bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. Catalysis of the reaction: ribulose-5-phosphate = 3,4-dihydroxy-2-butanone-4-phosphate + formate. Catalysis of the reaction: fumarate + toluene = benzylsuccinate.
