Hydrogen bonds between BP benzylic ring and adjacent base or backbone atoms
| Sequence context | Hydrogen bond | Occupancy (%) |
|---|---|---|
| CG*C | (BP)O7-HO7···O2(C17) | 85 |
| (BP)O8-HO8···O2(C7) | 54 | |
| (BP)O7-HO7···O4′(G18) | 12 | |
| TG*T | (BP)O7-HO7···O2(C17) | 91 |
| (BP)O8-HO8···O2(T7) | 64 | |
| (BP)O9-HO9···O4′(A8) | 18 |
Criteria for formation of hydrogen bonding: heavy atom–heavy atom distance <3.3 Å and donor-hydrogen-acceptor angle >140°.
