FIG. 4.

Phylogenetic tree of selected ABC proteins with other eukaryotic ABC proteins. Phylogeny was derived and is displayed according to the procedure outlined in Fig. 1, except that complete protein sequences were used instead of just the NBD. (A) Phylogenetic tree of ABCA proteins in seven eukaryotic genomes. (B) Phylogenetic tree of the ABCF proteins in Leishmania, with human and yeast proteins. lm, L. major; Tc, T. cruzi; Tb, T. brucei; Hs, H. sapiens; Dm, D. melanogaster; Ce, C. elegans; Dd, D. discoideum, Sc, S. cerevisiae.
