ENZYME entry: EC

Accepted Name
3-hydroxy-D-aspartate aldolase.
Alternative Name(s)
D-3-hydroxyaspartate aldolase.
Reaction catalysed
  • Threo-3-hydroxy-D-aspartate <=> glycine + glyoxylate
  • D-erythro-3-hydroxyaspartate <=> glycine + glyoxylate
Pyridoxal 5'-phosphate.
  • The enzyme, purified from the bacterium Paracoccus denitrificansy IFO 13301, is strictly D-specific as to the alpha-position of the substrate, but accepts both the threo and erythro forms at the beta- position.
  • The erythro form is a far better substrate (about 100 fold).
  • The enzyme can also accept D-allothreonine, D-threonine, erythro-3- phenyl-D-serine and threo-3-phenyl-D-serine.
  • Different from EC
  • Requires a divalent cation, such as Mg(2+), Mn(2+) or Co(2+).
