Abstract
The peptide N-Acetylaspartylglutamate (NAAG) is hydrolyzed by N-Acetylated-alpha-linked-acidic dipeptidase (NAALADase, glutamate carboxypeptidase II) into N-Acetylated aspartate (NAA) and glutamate. Hydrolysis can be measured as described in this unit by employing radiolabeled NAAG (NAA-[(3)H]glu) as the substrate. The occurrence of NAALADase activity in a wide range of tissues has implications for a variety of physiological purposes. The assay described here is useful for the analysis of NAALADase activity and its inhibition in brain synaptosomal preparations, tissue homogenates and tissue culture cell pellets.
