IUBMB Enzyme Nomenclature


Accepted name: L-erythro-3-hydroxyaspartate aldolase

Reaction: L-erythro-3-hydroxy-aspartate = glycine + glyoxylate

Other name(s): L-erythro-β-hydroxyaspartate aldolase; L-erythro-β-hydroxyaspartate glycine-lyase; erythro-3-hydroxy-Ls-aspartate glyoxylate-lyase

Systematic name: L-erythro-3-hydroxy-aspartate glyoxylate-lyase (glycine-forming)

Comments: A pyridoxal-phosphate protein. The enzyme, purified from the bacterium Paracoccus denitrificans NCIMB 8944, is strictly specific for the L-erythro stereoisomer of 3-hydroxyaspartate. Different from EC, erythro-3-hydroxy-D-aspartate aldolase. Requires a divalent cation.
