Lyase

(Science: 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.
