Fig 5. 600 MHz 1H NMR spectra of Hb A, rHb(αH87G) and rHb(βH92G).

Fig 5

Spectra are CO- and deoxyHb A (A, B), CO- and deoxy-rHb(αH87G) (C, D), and CO- and deoxy-rHb(βH92G) (E, F) between 10 and 16 ppm at pH 7.0 and 25°C. The hemoglobin concentrations of Hb A, rHb(αH87G) and rHb(βH92G) were 1 mM, 800 and 500 μM, respectively, on a heme basis in 0.05 M phosphate buffer (pH 7.0). In addition, rHb(αH87G) and rHb(βH92G) contained 10 mM imidazole.
