FIGURE 1. — The protein sequence alignments of Arabidopsis RGTA1, RGTA2, and their orthologs. A, the alignment of the full-length protein sequences of Arabidopsis RGTA1 (AtRGTA1), Arabidopsis RGTA2 (AtRGTA2), and rat Rab-GGT α subunit (RnRABGGTA). The predicted PPTA repeats are marked as I, II, III, IV, and V. The 12-aa insertion (HQKQDDEKQDDP) in the third PPTA repeat (III) of RGTA2 is underlined. B, alignment of the third PPTA repeats of Arabidopsis RGTA1, Arabidopsis RGTA2, and Rab-GGT α subunits of yeast (ScBET4), P. patens (PpRGTA1), rice (Os06g0677500), D. melanogaster (DmPTAR3), rat (RnRABGGTA), and human (HsRABGGTA). Black background and asterisk, identical residues; gray background and dot, similar residues.
