MetaCyc Gene-Ontology-Terms Class: GO:0016829 - lyase activity

Definition: 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.

Summary:
Note that enzymes of class EC:4.99.-.- should also be annotated to this term.

Parent Classes:
GO:0003824 - catalytic activity
