The enzyme aspartate ammonia-lyase (EC 4.3.1.1) catalyzes the chemical reaction
L-aspartate
\rightleftharpoons
The reaction is the basis of the industrial synthesis of aspartate.
This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is L-aspartate ammonia-lyase (fumarate-forming). Other names in common use include aspartase, fumaric aminase, L-aspartase, and L-aspartate ammonia-lyase. This enzyme participates in alanine and aspartate metabolism and nitrogen metabolism.
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and .
