From: Atp8 is in the ground pattern of flatworm mitochondrial genomes
Amino acid alignment of atp8 in flatworms and other lophotrochozoans: a gastrotrich (Lepidodermella squamata), annelids (Platynereis dumerilii and Sipunculus nudus), molluscs (Sepiella japonica and Ascobulla fragilis), a phoronid (Phoronopsis harmeri), a kamptozoan (Loxosomella aloxiata), a bryozoan (Bugula neritina), a brachiopod (Terebratalia transversa) and a nemertean (Micrura bella). Transmembrane regions are underlaid in light green. Putative triclad atp8 sequences were omitted because of their derivedness (for inclusion of triclad sequences, see Additional file 9)
