IntEnz Enzyme Nomenclature


Accepted name:
aspartate 4-decarboxylase
Other names:
L-aspartate β-decarboxylase
L-cysteine sulfinate acid desulfinase
aminomalonic decarboxylase
aspartate β-decarboxylase
aspartate ω-decarboxylase
aspartic β-decarboxylase

L-aspartate 4-carboxy-lyase
Systematic name:
L-aspartate 4-carboxy-lyase (L-alanine-forming)




A pyridoxal-phosphate protein. Also catalyses the decarboxylation of aminomalonate (formerly listed as EC, and the desulfination of 3-sulfino-L-alanine to sulfite and alanine.
