Cross-eyed stereo licorice images of the ensembles of the AA and CG simulations of S2-57 and the CG simulations of S3-155. A, B. Average structures of the AA and CG ensembles of S2-57. Aligned residues 78–188, green; residues 1–43, blue; helix 10, red; prolines, yellow space filling; remainder, silver. C. Average structure of the CG ensemble of six S3-155 simulations. Aligned residues 78–188, cyan; helix 5, green; residues 1–43, blue; helix 10, red; prolines, yellow space filling; remainder, silver. Red arrowhead, antiparallel helix 5 pair; white arrowhead, helix 5 hairpin. D, F. Aligned structures of the protein backbones of AA and CG ensembles for the S2-57 and the S3-155 ensemble, respectively. Aligned residues 78–188 in the double belt, green; prolines, yellow space filling; remainder of the double belt and all of the hairpins, silver.
