Fig. 1.

NMR ensemble and backbone representations of Rds3p. (A) Stereoview of overlay of deposited ensemble of 20 lowest-energy models of Rds3p. The N and C termini, which are at the rear of the structure as viewed, are marked, as are clusters 1, 2 and 3 (the zinc atom of cluster 1 is obscured in this view). Significant disorder is limited to the region adjacent to cluster 3 (residues 51–55; see Overall Structure of Rds3p) on the far right of the structure as shown. The structure is oriented with the β-triangle facing upward. (B) Corresponding stereoview of the lowest energy structure from the NMR ensemble shown in chainbow coloring as a backbone ribbon with cysteine sidechains.
