Fig. 1.

Crystallographic analysis of uncomplexed Brag2. (A) Structure of unbound Brag2. Regions discussed in the text are indicated. The Sec7 domain is in pink, the linker in yellow, and the PH domain in blue. The same color scheme is used in all figures. (B) Overlay of Brag2 from P2₁2₁2₁ space group (light pink) and C2₁ space group (dark pink), showing the flexibility of the Sec7 C-terminal subdomain. The flexible hinge region is in orange. The orientation is as in A. (C) Electrostatic potential surface of unbound Brag2. The view is rotated by 90° with respect to A.
