Figure 4
Different heparin-binding modes of APLP1 E2. The interactions of APLP1 E2 and the bound heparin chains are shown as schematic diagrams. Amino-acid side chains of individual protein chains are coloured magenta (chain a) or cyan (chain b). Heparin is coloured grey. Interactions between amino-acid side chains and sugar residues are highlighted by orange dashes with interaction distances indicated in Å. (a) Interactions of heparin chain a with APLP1 E2. (b) Interactions of heparin chain b with APLP1 E2. The interaction map was prepared with LIGPLOT (Wallace et al., 1995). |
