Low-temperature time-resolved spectroscopic study of the major light-harvesting complex of Amphidinium carterae

Original language description

The major light-harvesting complex of Amphidinium (A.) carterae, chlorophyll-a?chlorophyll-c 2?peridinin?protein complex (acpPC), was studied using ultrafast pump-probe spectroscopy at low temperature (60 K). An efficient peridinin?chlorophyll-a energy transfer was observed. The stimulated emission signal monitored in the near-infrared spectral region was stronger when redder part of peridinin pool was excited, indicating that these peridinins have the S1/ICT (intramolecular charge-transfer) state withsignificant charge-transfer character. This may lead to enhanced energy transfer efficiency from ?red peridinins to chlorophyll-a. Contrary to the water-soluble antenna of A. carterae, peridinin?chlorophyll-a protein, the energy transfer rates in acpPC were slower under low-temperature conditions. This fact underscores the influence of the protein environment on the excited-state dynamics of pigments and/or the specificity of organization of the two pigment?protein complexes.
