Mass balance status: Balanced.

Enzyme Commission Primary Name: 3-hydroxy-D-aspartate aldolase

Enzyme Commission Synonyms: D-3-hydroxyaspartate aldolase

Taxonomic Range: Bacteria

Standard Gibbs Free Energy (ΔrG in kcal/mol): 3.1899872Inferred by computational analysis [Latendresse13]

Enzyme Commission Summary:
A pyridoxal-phosphate protein. The enzyme, purified from the bacterium Paracoccus denitrificans IFO 13301, is strictly D-specific as to the α-position of the substrate, but accepts both the threo and erythro forms at the β-position. The erythro form is a far better substrate (about 100 fold). The enzyme can also accept D-allothreonine, D-threonine, D-erythro-3-phenylserine and D-threo-3-phenylserine. Different from EC 4.1.3.14, L-erythro-3-hydroxyaspartate aldolase. Requires a divalent cation, such as Mg2+, Mn2+ or Co2+.
