Assembly of (gp27-gp5*-gp5C)
; reprinted from . A, Domain organization of gp5. The maturation cleavage is indicated with the dotted line. Initial and final residue numbers are shown for each domain. B, Alignment of the octapeptide units composing the intertwined part of the C-terminal β-helix domain of gp5. Conserved residues are in bold print; residues facing the inside are underlined. The main chain dihedral angle configuration of each residue in the octapeptide is indicated at the top by κ (kink), β (sheet), and α (helix).
