Figure 3.

Three-dimensional solution structure of sublancin 168. (a) Ribbon diagram of the lowest energy conformer with helices colored in cyan, the loop regions, N- and C-termini colored pink, cysteine residues in yellow, and the carbohydrate moiety in orange. (b) Ensemble of the 15 lowest energy conformers depicting all backbone atoms. (c) Ball and stick representation of the lowest energy conformer with the loop region and termini in pink coming together to seal off one face of the helices. Exposed sulfur atoms are labeled.
