1 Fig. 6 Schematic illustration of the decreased conformational stability in the N92I mutant and its activation mechanism. Schematic illustration of the decreased conformational stability in the N92I mutant and its activation mechanism. In the wild type (black), a hydrogen bond interaction (blue line) is formed between Asp11 and Trp97. In the N92I mutant (red), the side chain of Ile92 sterically blocks the hydrogen bond interaction (magenta circle). The loss of this hydrogen bond in the N92I mutant increases the GDP-bound ground-state energy and hence accelerates the GDP dissociation by lowering the activation energy along the GDP dissociation reaction coordinate.
