The flexibility of the conserved 57DTAGQ61 motif is essential for Ras proper cycling in response to growth factors. Here, we increase the flexibility of the 57DTAGQ61 motif by mutating Gln61 to Gly. The crystal structure of the RasQ61G mutant reveals a new conformation of switch 2 that bears remarkable structural homology to an intermediate for GTP hydrolysis revealed by targeted molecular dynamics simulations ...
