Destruction of C-550 by ultraviolet radiation
Copyright policy )Destruction of C-550 by ultraviolet radiation
Abstract Low-temperature absorption spectra of spinach chloroplasts measured after different periods of ultraviolet radiation show that C-550 is destroyed by the ultraviolent treatment. Cytochrome b559 is oxidized and denatured so that it is no longer reducible by ascorbate. The light-induced fluorescence yield changes induced at low temperature diminish as C-550 is destroyed.
