Phospholipase D (PLD) is an enzyme that hydrolyzes the terminal phosphodiester bond of various phospholipids to generate phosphatidyl acid (PA) and a corresponding alcohol. PLD also catalyzes a transphosphatidylation reaction when alcohol is present as a nucleophilic donor. The transphosphatidylation reaction is important in the synthesis of scarce phospholipids and novel artificial phospholipids. PLD are widespread in plants, mammals and microroorganisms, such as bacteria and yeast. Streptomyces sp...
