Guanosine Diphosphate 34-37 eukaryotic translation elongation factor 1 alpha 1 Homo sapiens 0-5 31058500-6 2019 Additionally, molecular dynamics (MD) simulations indicate that enthalpic stabilization of GDP binding compared to GTP binding originates in the backbone hydrogen bonding network of EF-Tu. Guanosine Diphosphate 91-94 eukaryotic translation elongation factor 1 alpha 1 Homo sapiens 182-187 31058500-7 2019 In contrast, binding of GTP to EF-Tu is entropically driven by the liberation of bound water during the GDP- to GTP-bound transition. Guanosine Diphosphate 104-107 eukaryotic translation elongation factor 1 alpha 1 Homo sapiens 31-36 31058500-8 2019 GDP binding to the apo conformation of EF-Tu is both enthalpically and entropically favored, a feature unique among translational GTPases. Guanosine Diphosphate 0-3 eukaryotic translation elongation factor 1 alpha 1 Homo sapiens 39-44
