A) EPR spectra of hp53R2 and hRRM2 wild types and the mutants Q127V, Q127K, Q127E, Q127N, and Q165V, Q165K, Q165E, Q165N. B) EPR spectra of wide types and mutants F183Y, Y124W, Y124W/F183Y in hp53R2 and Y221F, Y162W, Y162W/Y221F in hRRM2. EPR spectra of human RRM2 and p53R2 proteins recorded at 20K in a Bruker 300E spectrometer with microwave power 0.1 mW, microwave frequency 9.375 GHz, and modulation amplitude 2.0 G.
