Figure 1
Crystal structure of BT2081 from B. thetaiotaomicron. (a) Ribbon diagram of the BT2081 monomer, showing the distinct N-terminal (green) and C-terminal (purple) domains. Helices (H1–H7) and β-strands (β1–β28) are indicated. (b) Diagram showing the secondary-structure elements of BT2081 superimposed on its primary sequence. The labeling of secondary-structure elements [colored by domain as in (a)] is in accord with PDBsum (http://www.ebi.ac.uk/pdbsum ), in which α-helices (H1, H3, H5 and H6), 310-­helices (H2, H4 and H7) and β-strands (β1–β28) are labeled sequentially, β-turns and γ-turns are designated by Greek letters (β, γ) and β-hairpins by red loops.
