Figure 1
Stereoview of the overall structure of brazzein. The N- and C-termini as well as the secondary-structure elements β-strands (β1–3) and α-helices (α1–2) are labelled. (a) Structure of a brazzein monomer. (b) Structure of a brazzein homodimer. One protomer is coloured as in (a), while the other protomer is coloured black. The sodium ion between the protomers is shown as a red sphere. (c) The coordination of the sodium ion. Interatomic distances (Å) are shown in red.
