Erythro-3-hydroxyaspartate ammonia-lyase

Erythro-3-hydroxyaspartate ammonia-lyase

In enzymology, an erythro-3-hydroxyaspartate ammonia-lyase (EC number|4.3.1.20) is an enzyme that catalyzes the chemical reaction

:erythro-3-hydroxy-Ls-aspartate ightleftharpoons oxaloacetate + NH3

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

This enzyme belongs to the family of lyases, specifically ammonia lyases, which cleave carbon-nitrogen bonds. The systematic name of this enzyme class is erythro-3-hydroxy-Ls-aspartate ammonia-lyase (oxaloacetate-forming). Other names in common use include 3-hydroxyaspartate dehydratase, erythro-beta-hydroxyaspartate dehydratase, erythro-3-hydroxyaspartate dehydratase, erythro-3-hydroxy-Ls-aspartate hydro-lyase (deaminating), and erythro-3-hydroxy-Ls-aspartate ammonia-lyase. It employs one cofactor, pyridoxal phosphate.
