Figure 2.
The Ypt1p/TRAPPI interface. At top, the complex is shown with Ypt1p in purple, except for switches I and II (orange) and the P-loop (yellow). The TRAPPI complex is white, except for the C-terminus of Bet3p-A (green). At bottom, Ypt1p has been pulled away from the TRAPPI surface and rotated by 180 ° about a vertical axis. Cα positions of residues within 4 Å of the interface are labeled and colored.
