An Outer Membrane Receptor of Neisseria meningitidis Involved in Zinc Acquisition with Vaccine Potential
Figure 2
The 22 β-strands are colored light grey, the 11 extracellular loops are white and the periplasmic turns are black. The histidine/aspartic acid stretches are boxed. The plug domain was modeled based on known Tdf structures. The amino acid sequence of loop 3 is shown with the cysteines in bold and the His/Asp-rich stretches underlined. Numbers indicate amino acid positions in the sequence of mature ZnuD.
