Figure 1.
ABC-F phylogeny. Cladogram produced using CLUSTAL-Ω and labeled with Swissprot species codes, which shows two bacterial orthologs of EttA (from A. tumefaciens and M. tuberculosis), one bacterial paralog of EttA (YfmR from B. subtillis), two non-ABC-F family proteins containing tandem ABC domains (eEF3 and ABCE1 from S. cerevisiae), and all ABC-F proteins from E. coli (red), S. cerevisiae (cyan), A. thaliana (purple), and H. sapiens (blue). Note that all of these ABC-F proteins, but neither eEF3 nor ABCE1, contain the PF12848 domain in addition to tandem ABC domains.
