Structure of the Rbg1fl–Tma46205–345 complex with sequence information. (A) A surface representation of the Tma46 C-terminal fragment (pink) enveloping Rbg1 (pale blue) is shown on the left. The individual components are shown color-coded on the right: the Tma46 C-terminal fragment (pink) and Rbg1 with the G-domain (pale blue, this includes the short β sheet formed by β5 and β9 connecting the S5D2L domain), the protuberance formed by the HTH and S5D2L domains (purple) and the TGS domain (blue). The GTP-binding pocket is also represented with the five G motifs colored as orange. A schematic domain organization of the structurally solved complex is also shown. (B) The component sequences and secondary structure elements of the crystallized complex are represented with the G-motifs (G1–G5) given in bold letters. Domain boundaries are indicated in the same color scheme as in Figure 1A.
