abstract Aromatic L-amino acid decarboxylase was purified from bovine brain for the first time by affinity chromatography using a monoclonal antibody to the enzyme, and it was compared with the decarboxylase purified from bovine adrenal medulla by the same procedure. The monoclonal antibody was produced from a hybridoma established for the enzyme highly purified from bovine adrenal medulla. The Mr values of brain and adrenal-medulla enzyme were both estimated to be approx. 100,000 by gel- permeation chromatography. SDS/polyacrylamide-gel electrophoresis revealed a single band with an apparent Mr of 50,000. Western immunoblot analysis showed that the antibody recognized each enzyme. With regard to substrate specificity, pH-dependence and effect of pyridoxal 5'-phosphate as a cofactor, both enzymes were similar.
