Figure 2. The PROPPIN family has two conserved lipid binding sites.
- Structurally annotated alignment of PROPPIN sequences for lipid-binding blades 5 and 6. Sequences were aligned with T-Coffee within each blade based on multiple alignment of primary sequences. Residues showing 100, 80 and 60% conservation across the different proteins are highlighted in red, blue and green respectively.
- Ribbon representation of the structural superposition of blades 5 (green) and 6 (pink). The sulfates and binding sites residues are shown in ball and stick model.
- Mutations in the indicated site 1 and site 2 residues reduce or eliminate binding to liposomes.
