GO Classification
Functions
aminoacylase activity / aspartoacylase activity / hydrolase activity, acting on ester bonds / metal ion binding
Processes
aspartate catabolic process / cellular amino acid biosynthetic process / cellular nitrogen compound metabolic process / central nervous system myelination / positive regulation of oligodendrocyte differentiation / small molecule metabolic process
Components
cytoplasm / cytosol / extracellular exosome / nucleus
General Function
Metal ion binding
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.
