Figure 1
Crystal structure of SSO2064 from S. solfataricus. (a) Stereo ribbon diagram of the SSO2064 monomer (chain A) color-coded from the N-terminus (blue) to the C-terminus (red). Helices (H1–H3) and β-strands (β1–β11) are indicated. The zinc ion is depicted as a gray sphere. (b) Diagram showing the secondary-structure elements of SSO2064 superimposed on its primary sequence. The labeling of secondary-structure elements is in accord with PDBsum (https://www.ebi.ac.uk/pdbsum ): α-helices are labeled H1 and H2, the 3₁₀-helix is labeled H3, the β-strands are labeled β1–β11, β-turns and γ-turns are designated by their respective Greek letters (β, γ) and red loops indicate β-hairpins.
