ENZYME entry: EC 4.3.1.27

Accepted Name
Threo-3-hydroxy-D-aspartate ammonia-lyase.
Alternative Name(s)
D-threo-3-hydroxyaspartate dehydratase.
Reaction catalysed
Threo-3-hydroxy-D-aspartate <=> oxaloacetate + NH(3)
Cofactor(s)
Pyridoxal 5'-phosphate.
Comment(s)
  • The enzyme, purified from the bacterium Delftia sp. HT23, also has activity against L-threo-3-hydroxyaspartate, L-erythro-3- hydroxyaspartate, and D-serine.
