A new enzymatic method for the synthesis of (/sup 14/C)pyridoxal 5-phosphate is presented. (/sup 14/C)Pyridoxal 5'-phosphate was synthesized from (/sup 14/C)pyriodoxine through the successive actions of pyridoxal kinase and pyrdoxamine 5'-phosphate oxidase in a reaction mixture containing ATP, (/sup 14/C)pyridoxine, and both enzymes. (/sup 14/C)Pyridoxal 5'-phosphate was isolated by omega-aminohexyl-Sepharose 6B column chromatography. The overall yield of the product was more than 60%, starting from 550 nmol of (/sup 14/C)pyridoxine. The radiochemical purity of the products, as determined by thin-layer and ion-exchange chromatography, was greater than 98%.
