Figure 7
Plot of pore radii against coordinates in the direction of the channel. Blue dots represent the data obtained using the protomeric OmpU structure with an intact N-terminal coil, while red dots indicate the data from protomeric OmpU with the N-terminal coil deleted. The two-stage narrowing of the pore is symbolized by the two narrowest points (3.29 and 3.09 Å). The coordinate of the narrowest point in the structure without the N-terminal coil (3.20 Å) corresponds well to the 3.09 Å point in the native structure.
