Fig. 2. Interactions within the ECLR and 114RVVSWF119 linker.

Fig. 2

a View of the 114RVVSWF119 six-residue peptide linker in the CD47BRIL-B6H12 crystal structure (green cartoon and sticks), and the insertion site of the 117SWF119 loop in the ECLR core. The ECD is shown as green cartoon and the TMD helices are colored blue (helix I), light green (helix II), orange (helix III) and light orange (helix V). The ECL1 is shown as orange cartoon and sticks. b A 90 degree rotation of CD47BRIL-B6H12 structure view shown in (a) highlighting the ECL1 hydrogen bonds (black dotted lines) between Y184 side chain and ECL2 (main-chain atoms shown as gray sticks and labeled), and between N188 side chain and ECL1 (orange sticks).
