Carbon-Nitrogen Lyases

Medical Definition:	Enzymes that catalyze the cleavage of a carbon-nitrogen bond by means other than hydrolysis or oxidation. Subclasses are the AMMONIA-LYASES, the AMIDINE-LYASES, the amine-lyases, and other carbon-nitrogen lyases. EC 4.3.
Guide Notes:	DF: C N LYASES
CAS Number:	EC 4.3
Previously Indexed:	Lyases (1966-1997)

Carbon-Nitrogen Lyases Categories.

	Amidine-Lyases - These enzymes catalyze the elimination of ammonia from amidines with the formation of a double bond. EC 4.3.2.
	Ammonia-Lyases - Enzymes that catalyze the formation of a carbon-carbon double bond by the elimination of AMMONIA. EC 4.3.1.
