Fig. 1: Overall structure of BBRF2Δ.

a Structure of BBRF2Δ. Helices and β-strands are specified and coloured cyan and magenta, respectively. The vector encoded residues are coloured grey. The N- and C-termini are indicated by spheres. The vector-encoding part of the N-terminal extension is coloured grey. The disordered loop is shown as a dashed line. b Topology diagram of BBRF2Δ. Secondary structural elements are not drawn to scale, and are coloured as in a. The boarders of the elements are specified. c Details of the hydrophilic core of BBRF2Δ, with α4 and α5 removed for clarity. The main chain oxygen and nitrogen atoms involved in the contact are indicated in subscript with the corresponding amino acids.
