ENZYME entry: EC 4.3.1.20

Accepted Name
erythro-3-hydroxy-L-aspartate ammonia-lyase.
Alternative Name(s)
3-hydroxyaspartate dehydratase.
erythro-3-hydroxyaspartate dehydratase.
erythro-3-hydroxy-Ls-aspartate hydro-lyase (deaminating).
erythro-beta-hydroxyaspartate dehydratase.
Reaction catalysed
(3R)-3-hydroxy-L-aspartate <=> NH4(+) + oxaloacetate
Comment(s)
  • The enzyme, which was characterized from the bacterium Paracoccus denitrificans NCIMB 8944, is highly specific for the L-isomer of erythro-3-hydroxyaspartate.
  • Different from EC 4.3.1.16 and EC 4.3.1.27.
  • Requires a divalent cation such as Mn(2+), Mg(2+), or Ca(2+).
  • Formerly EC 4.2.1.38.
