Amino Acid Decarboxylase in the Brain of Catfish

With the purpose to elucidate the mechanism of amino acids in the brain of fish, we have studied the glutamic decarboxylase in the fish brains following the techniques devise by Okumura et all, and examined the functions of various amino acid decarboxylase in the catfish brain. However, we did not find any decarboxylase activity in the catfish brain.
