FIG. 4.
Alignment of C. reinhardtii Ftr1 with Ftr1 homologues from other organisms. The alignment was generated by using the ClustalW algorithm and BioEdit software (34). Residues that are similar or identical in a majority (four) of sequences are shaded gray and black, respectively. A line above the alignment indicates the conserved RExxE motifs. GenBank accession numbers: C. reinhardtii Ftr1, AF478411; Synechocystis, BAA16870, S. cerevisiae Ftr1p, NP_011072; S. cerevisiae Fth1p, AF177330; S. pombe Fip1, AF177330; C. albicans CaFTR1, AF195775; and C. albicans CaFTR2, AF195776.
