Description Aspartate 4-decarboxylase.
Alternative names Aspartate-beta-decarboxylase;
Cysteine sulfinate desulfinase.
Catalyzed reaction L-aspartate = L-alanine + CO(2).
Cofactor Pyridoxal-phosphate.
Comments -!- Also catalyzes the decarboxylation of aminomalonate and the desulfination of 3-sulfino-L-alanine to sulfite and alanine.
-!- Formerly EC
The only validated sequences are from bacteria. The activity occurs also in fungi and metazoa (the rat enzyme appears to be membrane-bound) but no sequences similar to the bacterial ones are found in the genomes of these organisms.
