Figure 2. Conformational flexibility of the YaeT periplasmic domain.

Figure 2

(A-B) Superposition of the structure of YaeT21:359 presented here with that of YaeT21-351 determined by Kim et al. (PDB: 2qdf). The two structures are superimposed on POTRA1 and 2 (A) or POTRA3 and 4 (B). The color scheme for YaeT21:359 is the same as in Figure 1. The color scheme for Kim’s structure is as follows: POTRA1 – magenta; POTRA2 – blue; POTRA3 – dark green; POTRA4 – raspberry. (C-E) Interfaces between POTRA domains 1 and 2 (C); 2 and 3 (D) and 3 and 4 (E). Interacting residues are shown as sticks and secondary structure elements are shown as cartoon representation. A semitransparent surface representation is shown to highlight the extent of surface interaction between the domains.
