Figure 5

Conversion between and stability of oxidation states of SeShp and SeHtsAHis. (A) Optical absorption spectra of 6 μM hemiSeShp from the oxidation of hemoSeShp with ferricyanide (dashed curve) and hemoSeShp obtained from the reduction of hemiSeShp with dithionite (solid curve). The hemoSeShp spectrum was recorded after the removal of excess dithionite. (B) Optical absorption spectra of 5 μM dithionite-treated holoSeHtsAHis in the presence of excess dithionite (dashed line) and after the removal of dithionite (solid line).
