Abstract

<p>(A) Structural comparison with the catalytic core of Rabex-5. Four residues important for the GEF activity of Rabex-5 and corresponding Lpg0393 residues are shown in sticks (<i>left</i>) and highlighted (<i>right</i>). Asp313 and Tyr354 are identically conserved in Lpg0393, while Pro317 and Glu351 are substituted by unrelated amino acids. (B) Topological comparison with the catalytic core of Rabex-5. The domain organization is reversed, and the topology of the helical bundle domain is reversed in the two proteins. (C) Structure-based sequence alignment. The N-terminal domain of Lpg0393 and the Vps9 domains of Rabex-5 and <i>Arabidopsis</i> Vps9a are aligned. The secondary structural elements of Lpg0393 and Rabex-5 are shown at the top and bottom of the alignment, respectively. The four highlighted residues in <i>A</i> are indicated by arrows.</p
