ENZYME - 4.3.1.20 erythro-3-hydroxy-L-aspartate ammonia-lyase

Accepted Name
erythro-3-hydroxy-L-aspartate ammonia-lyase
Alternative Name(s)
3-hydroxyaspartate dehydratase
erythro-3-hydroxyaspartate dehydratase
erythro-3-hydroxy-Ls-aspartate hydro-lyase (deaminating)
erythro-beta-hydroxyaspartate dehydratase
Reaction catalysed
(3R)-3-hydroxy-L-aspartate = oxaloacetate + NH4(+)
Comment(s)
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 4.3.1.16 and EC 4.3.1.27. Requires a divalent cation such as Mn(2+), Mg(2+), or Ca(2+). Formerly EC 4.2.1.38.
