| carbon-oxygen lyases | <enzyme> Enzymes that catalyze the cleavage of a carbon-oxygen bond by means other than hydrolysis or oxidation. Registry number: EC 4.2 (12 Dec 1998) |
|---|---|
| carbon-sulfur lyases | <enzyme> Enzymes that catalyze the cleavage of a carbon-sulfur bond by means other than hydrolysis or oxidation. Registry number: EC 4.4 (12 Dec 1998) |
| carboxy-lyases | <enzyme> Enzymes that catalyze the nonhydrolytic addition or removal of a carboxyl group to or from a compound. They include the carboxylases and decarboxylases. Registry number: EC 4.1.1. (12 Dec 1998) |
| phosphorus-oxygen lyases | <enzyme> Enzymes that catalyze the cleavage of a phosphorus-oxygen bond by means other than hydrolysis or oxidation. Registry number: EC 4.6 (12 Dec 1998) |
| polysaccharide-lyases | <enzyme> A group of carbon-oxygen lyases. These enzymes catalyze the breakage of a carbon-oxygen bond in polysaccharides leading to an unsaturated product and the elimination of an alcohol. Registry number: EC 4.2.2. (12 Dec 1998) |
| hydro-lyases | <enzyme> Enzymes that catalyze the removal of water from a substrate by breakage of a carbon-oxygen bond, leading to formation of a double bond. The recommended name is usually dehydratase. The term synthase or hydratase is used when the reverse aspect of the reaction is dominant. Registry number: EC 4.2.1. (12 Dec 1998) |
| intramolecular lyases | <enzyme> Enzymes of the isomerase class that catalyze reactions in which a group can be regarded as eliminated from one part of a molecule, leaving a double bond, while remaining covalently attached to the molecule. Registry number: EC 5.5 (12 Dec 1998) |
| oxo-acid-lyases | <enzyme> Enzymes that catalyze the cleavage of a carbon-carbon bond of a 3-hydroxy acid. Registry number: EC 4.1.3. (12 Dec 1998) |
| lyases | <enzyme> A class of enzymes that catalyze the cleavage of c-c, c-o, and c-n, and other bonds by other means than by hydrolysis or oxidation. Registry number: EC 4. (12 Dec 1998) |
