Crystal structure of BB2672 from B. bronchiseptica. (a) Stereo ribbon diagram of the BB2672 protomer color-coded from the N-terminus (blue) to the C-terminus (red). Helices (H1–H6) and β-strands (β1–β7) are indicated. (b) Diagram showing the secondary-structure elements of BB2672 superimposed on its primary sequence in accordance with PDBsum (https://www.ebi.ac.uk/pdbsum
). For BB2672, the α-helices (H1, H3 and H4), 310-helices (H2, H5 and H6), β-strands (β1–β7) and β-turns (β) are indicated. |
