Enzyme Information
| 4.3.1.27 |
Threo-3-hydroxy-D-aspartate ammonia-lyase.
based on mapping to UniProt B2DFG5
Threo-3-hydroxy-D-aspartate = oxaloacetate + NH(3).
-!- 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 4.3.1.20 and EC 4.3.1.16. -!- Requires a divalent cation such as Mn(2+), Co(2+) or Ni(2+).
