Synthesis of 5'-phosphatidylnucleosides by phospholipase D-catalyzed transphosphatidylation

Phospholipase D from Streptomyces effectively catalyzed the transfer reaction of the phosphatidyl residue from phosphatidylcholine to the 5'-hydroxyl group of nucleosides. A variety of 5'-phosphatidylnucleosides were prepared by this reaction in high yields. Some of them showed marked antitumor activities in mice.
