& Chwan-Deng Hsiao | | | | Figure 2. Stereo view of the superposition of the C and the G motifs of Toc34 and H-ras-p21.
a, C s of H-rasp-21−GDP (PDB accession code 4Q21) and Toc34 are shown in magenta and green, respectively. Switches I and II, and the longest loop of Toc34 are labeled. b, The structural overlay of the G motifs of Toc34−GDP and Ras−GDP, colored as in (a). Two candidates, Ser 68 or Ser 72 and Gln 71 or Asn 104, in Toc34 have been proposed to function like Thr 35 and Gln 61 of Ras, respectively (see text).
