| lyase | <enzyme> An enzyme of the EC Class 4, that strips a group from a molecule to form a double bond or adds a group to a double bond. A lyase catalyses the nonhydrolytic removal of a group from a substrate with the resulting formation of a double bond. The reverse reaction is performed by a synthetase. The group include decarboxylases, aldolases and dehydratases. (14 Oct 1997) |
