A Deeply Branching Lineage in Heterolobosea (Discoba) With Multiflagellated and Multigrooved Life Stages

The eukaryotic phylum Heterolobosea includes #flagellates, #amoebae, and amoeboflagellates, notably the brain-eating amoeba Naegleria fowleri. New transcriptome data reveal the #evolution of Heterolobosea and two instances of genetic code alteration.

Based on this, Myo2A-1 and Myo2B-1 (both N-terminal) might work for N. fowleri? But this region is before the SH3-like predicted fold, with no predicted structure. These N-terminal regions vary widely in length outside of Heterolobosea and is only around 50-60% identical with the Naegleria genus.

𝘕. f𝘰𝘸𝘭𝘦𝘳𝘪 is part of Heterolobosea—a bizarre lineage that independently evolved amoeboid motion. It’s not closely related to Amoebozoa (“true” amoebas), but closer to Euglena.
