context_page_description: In enzymology, an aspartate 4-decarboxylase is an enzyme that catalyzes the chemical reaction
  L-aspartate L-alanine + CO₂
  Hence, this enzyme has one substrate, L-aspartate, and two products, L-alanine and CO₂. This reaction is the basis of the industrial synthesis of L-alanine.
  This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is L-aspartate 4-carboxy-lyase. Other names in common use include desulfinase, aminomalonic decarboxylase, aspartate beta-decarboxylase, aspartate omega-decarboxylase, aspartic omega-decarboxylase, aspartic beta-decarboxylase, L-aspartate beta-decarboxylase, cysteine sulfinic desulfinase, L-cysteine sulfinate acid desulfinase, and L-aspartate 4-carboxy-lyase. This enzyme participates in alanine and aspartate metabolism and cysteine metabolism. It employs one cofactor, pyridoxal phosphate.
