15- cis-β-Carotene found in the reaction center of spinach photosystem II

Solvent extraction at ∼4°C in complete darkness, and subsequent analysis by high-pressure liquid chromatography (at ∼4°C) using an apparatus equipped with a two-dimensional diodearray detector, spectroscopically identified 15- cis-β-carotene in the reaction center (RC) of spinach photosystem 11 (PS...

Description
Summary:Solvent extraction at ∼4°C in complete darkness, and subsequent analysis by high-pressure liquid chromatography (at ∼4°C) using an apparatus equipped with a two-dimensional diodearray detector, spectroscopically identified 15- cis-β-carotene in the reaction center (RC) of spinach photosystem 11 (PS 11). The result revises a previous conclusion that /3-carotene bound to the PS 11 RC takes the all-trans configuration [Fujiwara, H., Hayashi, H., Tasumi, M., Kanaji, M., Koyama, Y. and Satoh, K. (1987) Chem. Lett. 2005–2008], and generalizes the concept established for purple photosynthetic bacteria that 15- cis-carotenoid is naturally selected by the photosynthetic reaction centers.
