Electrostatic contacts between angiogenin and the RNA duplex. Hydrogen bonds and electrostatic interactions up to 5 Å are shown as dashed lines. The interatomic distance (Å) for each contact is given. (a) Contacts between the RNA duplex and angiogenin helix 3. (b) Contacts between the RNA duplex and angiogenin helix 4. (c) Contacts between the RNA duplex and angiogenin helix 2. |
