Table 2. Comparison of phosphate hydration in A-DNA octamers (Eisenstein & Shakked, 1995 ▶) and in d(CCCCGGTACCGGGG)2 .
| Oligomer | Resolution (Å) | Phosphate hydration | |
|---|---|---|---|
| Total atoms† | No. of water atoms/No. of hydrated O atoms | ||
| GGGCGCCC | 1.75 | 28 | 37/24 |
| GGCCGGCC | 2.1 | 28 | 35/22 |
| CCCCGGGG | 2.5 | 28 | 29/18 |
| CCCCGGTACCGGGG | 1.65 | 52 | 11/10 |
Only O1P and O2P phosphate O atoms are taken into consideration.
