Theoretical IR Spectroscopy Based on QM/MM Calculations Provides Changes in Charge Distribution, Bond Lengths, and Bond Angles of the GTP Ligand Induced by the Ras-Protein
The GTPase Ras p21 is a crucial switch in cellular signal transduction. Fourier transform infrared (FTIR) spectra of the substrate guanosine triphosphate (GTP) show remarkable changes when it binds to the enzyme. The reduced band widths indicate that the flexible GTP molecule is guided by the protei...
