| Abstract: | The reaction kinetics of fully oxidized flavodoxin from Clostridium MP with the hydrated electron have been investigated by the pulse radiolysis method. Four spectrally distinct processes have been observed with the ultimate formation of the singly reduced flavin form of the protein. The last two species obtained in the reaction sequence are spectrally similar, and are connected through a reaction which is first order. It is proposed that this reaction involves a protein conformational alteration. |
