Inorganic pyrophosphate-dependent phosphofructokinase
(PPi-PFK) of the amitochondriate eukaryote
Mastigamoeba balamuthi was sequenced and showed about 60%
identity to PPi-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.
