Fig. 2.

Rooting with ABCE shows eukaryotic-like ABCFs nesting within bacterial-like ABCFs, with YheS as the sister group to the eukaryotic-like clade. Maximum likelihood phylogeny of representatives across the ABCF family, and ABCE sequences from the UniProt database. Branch support from 200 bootstrap replicates with RaxML (MBP), 1000 UFB replicates with IQ-TREE and BIPP is indicated with the key in the inset box. Branch lengths are proportional to amino acid substitutions as per the inset scale bar.
