BRITE hierarchy
Sysname
threo-3-hydroxy-L-aspartate ammonia-lyase (oxaloacetate-forming)
Reaction(IUBMB)
threo-3-hydroxy-L-aspartate = oxaloacetate + NH3 [RN:R05758]
Reaction(KEGG)
Substrate
threo-3-hydroxy-L-aspartate [CPD:C11511]
Product
oxaloacetate [CPD:C00036];
NH3 [CPD:C00014]
Comment
A pyridoxal-phosphate protein. The enzyme, purified from the bacterium Pseudomonas sp. T62, is highly specific, and does not accept any other stereoisomer of 3-hydroxyaspartate. Different from EC 4.3.1.20, erythro-3-hydroxy-L-aspartate ammonia-lyase and EC 4.3.1.27, threo-3-hydroxy-D-aspartate ammonia-lyase. Requires a divalent cation such as Mn2+, Mg2+, or Ca2+.
History
EC 4.3.1.16 created 2001, modified 2011
