Table 5. Variation during helical twisting measured by HHPs, the number of protomer pairs per HHP, and the MADc observed for protomers resembling C-actin structures within shortened bare half helices adjacent to the cofilactin/bare actin boundary, as probed by HS-AFM.
The total number of HHPs observed was 32. The total number of protomer pairs used for estimating MADc was calculated by multiplying the number of protomer pairs by the number of HHPs.
| The number of protomer pairs per HHP | HHP (nm) | MADc (nm) | The number of HHPs (proportion) | The total number of protomer pairs |
|---|---|---|---|---|
| 3.5 | 22.2±0.2 | 6.3±0.1 | 2 (5.9%) | 7 |
| 4.5 | 26.1±1.4 | 5.8±0.3 | 21 (61.8%) | 94.5 |
| 5.5 | 28.5±0.9 | 5.2±0.2 | 9 (32.4%) | 49.5 |
