ENZYME entry: EC

Accepted Name
Erythro-3-hydroxy-L-aspartate ammonia-lyase.
Alternative Name(s)
3-hydroxyaspartate dehydratase.
Erythro-3-hydroxy-L(s)-aspartate hydro-lyase (deaminating).
Erythro-3-hydroxyaspartate dehydratase.
Erythro-beta-hydroxyaspartate dehydratase.
Reaction catalysed
Erythro-3-hydroxy-L-aspartate <=> oxaloacetate + NH(3)
Pyridoxal 5'-phosphate.
  • 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 and EC
  • Requires a divalent cation such as Mn(2+), Mg(2+), or Ca(2+).
  • Formerly EC
