Helix-20 in EBOV NP core indicates an essential hydrophobic pocket. (A) Comparison of EBOV NPcore and NiV NP. Both structures are shown as surface and colored gray. EBOV NPcore Helix-20 and NiV P50 are shown as cartoon, colored salmon red and cyan, respectively. (B) Formation of the hydrophobic pocket. Main chain is shown in cartoon and hydrophobic residues are shown in stick, colored in red by hydrophobicity. (C) Interaction of Helix-20 with hydrophobic pocket. Hydrophobic pocket are shown in surface, Helix-20 are displayed in ribbon and stick, colored in red by hydrophobicity. (D) Primary sequence alignment of members of the filoviridae family. Highly conserved residue in Helix-14, Helix-15, Helix-19, and Helix-20 are indicated by yellow arrow
