Figure 4From: The substrate specificities of sunflower and soybean phospholipases D using transphosphatidylation reactionEffect of other phospholipid classes on PC hydrolysis by PLD. All the phospholipids were sonicated separately and mixed with preformed PC vesicles in the assay medium at a 1/1 molar ratio. Sunflower PLD activity was assayed by measuring water-soluble choline as described in Materials and Methods. The results are representative of three experiments.Back to article page
