Neither phosphagens nor phosphagen phosphotransferase activity could be detected in Fasciola hepatica, Hymenolepis diminuta, Moniezia expansa or in the plerocercoids of Ligula intestinalis. The plerocercoids of Schistocephalus solidus, however, possess an active taurocyamine phosphotransferase, although it too contains no detectable phosphagens. The taurocyamine phosphotransferase of S. solidus has an absolute requirement for a divalent metal ion and ATP could not be replaced by ITP, GTP, CTP or UTP as the phosphate donor. The role of phosphagens in helminths is discussed.
在肝片吸虫、微小膜壳绦虫、扩展莫尼茨绦虫或鲤蠢绦虫的裂头蚴中均未检测到磷酸原或磷酸原磷酸转移酶活性。然而,坚实多头绦虫的裂头蚴具有活性的牛磺酸胺磷酸转移酶,尽管其也不含可检测到的磷酸原。坚实多头绦虫的牛磺酸胺磷酸转移酶绝对需要二价金属离子,并且ATP不能被ITP、GTP、CTP或UTP替代作为磷酸供体。文中讨论了磷酸原在蠕虫中的作用。
