Inorganic pyrophosphate-dependent phosphofructokinase (PP(i)-PFK) of the amitochondriate eukaryote Mastigamoeba balamuthi was sequenced and showed about 60% identity to PP(i)-PFKs from two eubacteria, Propionibacterium freudenreichii and Sinorhizobium meliloti. These gene products represent a newly recognized lineage of PFKs. All four lineages of group II PFKs, as defined by phylogenetic analysis, contained both prokaryotic and eukaryotic species, underlining the complex evolutionary history of this enzyme.
对无线粒体真核生物巴氏鞭毛虫(Mastigamoeba balamuthi)的无机焦磷酸依赖性磷酸果糖激酶(PP(i)-PFK)进行了测序,结果显示它与两种真细菌——费氏丙酸杆菌(Propionibacterium freudenreichii)和苜蓿中华根瘤菌(Sinorhizobium meliloti)的PP(i)-PFK具有约60%的同一性。这些基因产物代表了一种新确认的磷酸果糖激酶谱系。系统发育分析所定义的第II组磷酸果糖激酶的所有四个谱系都包含原核生物和真核生物物种,这突出了该酶复杂的进化历史。
