biological significance of phosphoenolpyruvate carboxykinase in a cestode parasite, raillietina echinobothrida and effect of phytoestrogens on the enzyme from the parasite and its host, gallus domesticus.phosphoenolpyruvate carboxykinase (pepck) is involved in glycolysis in the cestode parasite, raillietina echinobothrida; whereas, it executes a gluconeogenic role in its host, gallus domesticus. because of its differing primary function in the cestode parasite and its host, this enzyme is regarded as a plausible anthelmintic target. hence, the biological significance of pepck in the parasite was analysed using sirna against pepck from r. echinobothrida (repepck). in order to find out the functio ...201728485262
