Fig. 3. Pattern of main-chain hydrogen bonds of -strands of CspA and 1b11. Interstrand backbone hydrogen bonds are shown as dashed lines, and residues are shown as circles; small circles indicate residues pointing into the barrel. Hydrogen bonding from 1- 3 of CspA (dark blue) to 4- 5 of CspA (light blue) has been recapitulated in 1b11 by hydrogen-bonding to S1-derived residues in 4 and 6 (gray). Residues in 1b11 that are colored white have no structural equivalent in CspA.
