The predicted water probabilities and HSs correctly reproduce differences between phosphate hydration in the A and B forms. (a) Phosphate hydration in the A-DNA structure with PDB code 6l75 (Jhan et al., 2021). The phosphates are bridged by water molecules in accordance with the `economy of hydration' principle. (b) Phosphate groups hydrated separately in the B-DNA structure with PDB code 7m7n (Gregory et al., 2021). |
