Supplementary information

Aspartoacylase also known by its abbreviation ASPA is an enzyme that breaks down N-acetyl-L-aspartate into aspartate and acetate. It has a mass of about 60 kDa. ASPA is highly expressed in the brain especially in oligodendrocytes which are a type of central nervous system cell responsible for producing the myelin sheath that surrounds nerve cells. Its enzymatic activity is dependent on divalent metal ions which are required for its function.

Biological function summary

ASPA plays an important role in myelin sheath maintenance and acetate metabolism. This protein doesn't form part of a complex but acts independently in the cytoplasm and peroxisomes of cells. Its function is significant for the provision of acetate for lipid synthesis which is necessary for myelin production. By regulating N-acetyl-L-aspartate levels in the brain ASPA activity is linked directly to protecting nerve cells' structural integrity.

Pathways

The ASPA enzyme is involved in the aspartate and acetyl-CoA pathways which are central to cellular energy balance and lipid metabolism. Its enzymatic role facilitates the recycling of acetate which is vital to the synthesis of myelin lipids. The relationship of ASPA with enzymes like acetyl-CoA synthetase highlights its involvement in broader biochemical pathways fundamental to cell metabolism and growth.

Deficiencies in ASPA are linked to Canavan disease a rare and inherited neurodegenerative condition characterized by white matter sponginess and loss of motor skills. This disorder results from mutations in the ASPA gene leading to dysfunctional enzyme activity. Additionally changes in ASPA expression levels might contribute to demyelinating disorders where proteins like myelin basic protein are also often involved making ASPA an important target for studies exploring nervous system diseases.

Target data

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 acts as a scavenger of NAA from body fluids.
