Pulse radiolytic investigation of single heme group reduction in hum an methemoglobin.

The Journal of Biological Chemistry
J R ClementL M Dorfman


Reduction of one of the four heme groups of human aquomethemoglobin A has been investigated by the pulse radiolysis method. The reactivity of e-a-q, the hydrated electron, with methemoglobin was determined by observing this species directly. The separate reactions of the hydroxy yl radical and hydrogen atom, as well as of e-a-q, were studied by observing absorbance changes in the protein spectrum over the wavelength range 290 to 600nm, with appropriate scavengers in solution...
