Fig. 1. CryoEM structure of the V. cholerae type IV competence pilus secretin PilQ.

Fig. 1

a Model (cartoon in dark red) and cryoEM density (dark gray transparent) of symmetrized Vibrio cholerae PilQ (VcPilQ) is shown from the side (left) and cut through the center (right). The putative outer membrane region is represented in a light blue rectangle. b The atomic model of the VcPilQ multimer is shown (right). One chain is shown by itself (left). The putative outer membrane region is represented in a light blue rectangle. Dashed lines represent the different domains of the VcPilQ structure: AMIN (not shown), N0 (gray/dark blue), coil (purple), N3 (green), secretin (yellow), beta lip (sky blue). The gate region is labeled on the monomer.
