Figure 1.
Figure 1. (a) The monomer structure of XC5848 color-coded from blue (N-terminal) to red (C-terminal). Distinct interactions between the N-terminal residues with the extended 3/ 2 hairpin were circled in red and shown expanded in (b). (b) The 10 N-terminal residues were marked in blue, while other residues in red. The conventional H-bonds/salt-bridges were annotated in dotted green lines, while unconventional CH bonds in dotted gray lines. The unique bonding force at the N-terminal region are: (1) K3C O R55H^N; (2) Y4OH R55NH; (3) Y4OH R59O^ ; (4) A5H^N R55C O; (5) H7C O N64N^ ; (6) Y9H^N S63C O; (7) Y9C O S63H^N; (8) Y9OH D84O^ ; (9) T10C O Q12H^N; (10) W82C^ 3H Y54; (11) P6C^ H W82. (c) The dimer structure of XC5858. The interface is mainly comprised of helix-helix interactions, which were shown expanded in (d). (d) The interaction forces at this interface: (1) K23N^ E19O^ ; (2) H20N^ E19O^ ; (3) H20N^ Q12O^ and vice versa.
