In enzymology, a threo-3-hydroxyaspartate ammonia-lyase (EC 4.3.1.16) is an enzyme that catalyzes the chemical reaction

threo-3-hydroxy-L-aspartate oxaloacetate + NH3

Hence, this enzyme has one substrate, threo-3-hydroxy-L-aspartate, and two products, oxaloacetate and NH3.

Nomenclature

This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is threo-3-hydroxy-L-aspartate ammonia-lyase (oxaloacetate-forming). Other names in common use include threo-3-hydroxyaspartate dehydratase, L-threo-3-hydroxyaspartate dehydratase, and threo-3-hydroxy-L-aspartate ammonia-lyase.
