Table 2.
Secondary structural analyses of Stx2c/c and Stx2d/d before and post exposure to heat (PEH).
| Toxin | Helix, % (SD *) | Strand, % (SD) | Turns, % (SD) | Unordered, % (SD) |
|---|---|---|---|---|
| Stx2c/c | 31.2 (0.9) | 26.3 (1.6) | 10.6 (0.3) | 31.9 (1.0) |
| Stx2d/d | 31.0 (1.0) | 25.3 (1.5) | 20.0 (0.7) | 23.6 (0.8) |
| Stx2c/c PEH | 18.4 (0.5) | 33.4 (1.3) | 11.6 (0.3) | 36.6 (1.0) |
| Stx2d/d PEH | 12.5 (0.4) | 37.9 (2.0) | 11.8 (0.4) | 37.8 (1.2) |
* SD: standard deviation. The errors are the normalized root-mean-square deviation of 15 of the best-fit solutions.
