Abstract excerpt

Fourier transform infrared (FTIR) spectroscopy in the CO stretch bands combined with temperature derivative spectroscopy (TDS) was used to characterize intermediate states obtained by photolysis of two sperm whale mutant myoglobins, YQR (L29(B10)Y, H64(E7)Q, T67(E10)R) and YQRF (with an additional I107(G8)F replacement). Both mutants assume two different bound-state conformations, A(0) and A(3), which can be...
