Comparative quantitative analysis of phylloquinone content and photochemically competent P‐700 has been performed on photosystem I particles subjected to photolysis with ultraviolet irradiation. Nonirradiated control particles exhibit a phylloquinone/P‐700 stoichiometry of 1.9 ± 0.2. Photolysis of the photosystem I particles induces a progressive depletion of phylloquinone, however, photochemistry as assayed at room temperature by the photooxidation of P‐700 is unaffected. These data are not… Expand
