Figure 5. Structural impact of G12D and G12V mutations on GTP-bound substate preference. A, Distance distribution within 3P structure between the hydroxyl (OH) atom of residue Y32 and closest γ-phosphate (called here O1G) atom of GTP or GTP analogues, which was used to define hydrogen (H)-bonding subtypes: water-mediated (WM) H-bond, direct H-bond, and no H-bond. 3P substate preference within WT (B), G12D (C), and G12V (D) structures.
