Figure 3
Several key interdomain interactions are absent in SaDltA. (a) Close-up view of the short loop (Thr325–Gly328) linking β-strands β16 and β17 of SaDltA (orange and blue, chain A) and the equivalent region in B. cereus (gray). Hydrogen-bond interactions are shown as dotted lines. Note that the interaction of Lys345 with Glu410 and Gln401 is absent in the structure of S. aureus DltA. (b) Left: close-up view of the hydrogen-bond interactions between Arg268 in the N-lobe and Ser403 and Val405 in the C-lobe of SaDltA (orange and blue, chain A). Right: close-up view of the hydrogen-bond interactions observed in the equivalent region of B. cereus DltA (gray; PDB entry 3fcc). Hydrogen-bond interactions are shown as dotted lines. |
