Secondary Accession Numbers
  • 5827
  • HMDBP04431
Name Aspartoacylase
Synonyms
  1. ACY-2
  2. Aminoacylase-2
Gene Name ASPA
Protein Type Enzyme
Biological Properties
General Function Involved in hydrolase activity, acting on ester bonds
Specific Function Catalyzes the deacetylation of N-acetylaspartic acid (NAA) to produce acetate and L-aspartate. NAA occurs in high concentration in brain and its hydrolysis NAA plays a significant part in the maintenance of intact white matter. In other tissues it act as a scavenger of NAA from body fluids.
Pathways
  • Alanine, aspartate and glutamate metabolism
  • Aspartate Metabolism
  • Canavan Disease
  • Histidine metabolism
  • Hypoacetylaspartia
