A pyridoxal-phosphate protein. The enzyme, purified from the bacterium Delftia sp. HT23, also has activity against L-threo-3-hydroxyaspartate, L-erythro-3-hydroxyaspartate, and D-serine. Different from EC 22.214.171.124, erythro-3-hydroxy-L-aspartate ammonia-lyase and EC 126.96.36.199, threo-3-hydroxy-L-aspartate ammonia-lyase. Requires a divalent cation such as Mn2+, Co2+ or Ni2+.
