Crystal structure of Jann_2411 from Jannaschia sp. strain CCS1. (a) Stereo ribbon diagram of the Jann_2411 monomer color-coded from the N-terminus (blue) to the C-terminus (red). Helices H1–H9 and β-strands (β1−β6) are indicated. (b) Diagram showing the secondary-structure elements of Jann_2411 superimposed on its primary sequence. The labeling of secondary-structure elements is in accord with PDBsum (https://www.ebi.ac.uk/pdbsum
), where α-helices are labeled sequentially (H1, H2, H3 etc.), β-strands are labeled (A, B, C) according to the β-sheets to which they are assigned, β-turns and γ-turns are designated by their respective Greek letters (β, γ) and red loops indicate β-hairpins. For Jann_2411, the α-helices (H2–H7 and H9), 310-helices (H1 and H8), β-sheets (A–C, comprising strands β1–β2, β3–β4 and β5–β6, respectively), β-turns (β) and β-hairpins are indicated. |
