Before revision:  The 9 GHz EPR spectrum of the Aurora-A kinase was measured in order to study the dynamics of the MTSL spin label attached within the activation loop , MD provided information about the different motional contributions to the overall dynamics of the MTSL and about interactions between the MTSL and the residues of the protein . Data obtained from MD were seen to be in good agreement with those obtained from QM performed in previous work and with the experimental EPR data .
After revision:  The 9 GHz EPR spectrum of the Aurora-A kinase in solution and the residues of the protein . Data obtained from MD were seen to be in good agreement with those obtained from QM performed in previous work and with the experimental EPR data .
