Figure 2
(a) View from the top down the axis of the VapB β-barrel. Side chains of residues forming the hydrophobic core are represented as sticks. (b) Cartoon representation of streptavidin (PDB entry 1stp; Weber et al., 1989BB29) coloured from dark blue to red from the N-terminus to the C-terminus. Biotin is shown as spheres. (c) VapB coloured by B factor (blue, low; red, high) and oriented as streptavidin with respect to strand β1 (note that the structural alignment generated by DALI is different). The loops at the top exhibit high B factors and double backbone conformations for residues that are represented as sticks.
