Fig. 1. Crystal structure of KpBest.

Fig. 1

(A & B) Ribbon diagram of the KpBest pentamer with each protomer colored differently, (A) as viewed from outside the membrane and (B) as viewed from the side (rotated 90° through × axis). (C & D) Electrostatic potential at the molecular surface viewed as in A & B, respectively). The contour level is at ±5 kT/e red for negative potential and blue for positive potential. Membrane boundaries in B & D were calculated by OPM server. (E) 2D topology of a protomer, colored spectrally from dark blue at its N-terminal segment to red at its C-terminal segment. (F) Ribbon diagram of a protomer. Colored as in E.
