Aspartate Ammonia-Lyase
An enzyme that catalyzes the conversion of aspartic acid to ammonia and fumaric acid in plants and some microorganisms. EC 4.3.1.1.
Phenylalanine Ammonia-Lyase
An enzyme that catalyzes the deamination of PHENYLALANINE to form trans-cinnamate and ammonia.
Ammonia
A colorless alkaline gas. It is formed in the body during decomposition of organic materials during a large number of metabolically important reactions. Note that the aqueous form of ammonia is referred to as AMMONIUM HYDROXIDE.
Ammonia-Lyases
Enzymes that catalyze the formation of a carbon-carbon double bond by the elimination of AMMONIA. EC 4.3.1.
