1. Singlet and triplet state transitions of carotenoids in the antenna complexes of higher-plant photosystem

Author

Croce, Roberta, Mozzo, Milena, Morosinotto, Tomas, Romeo, Alessandro, Hienerwadel, Rainer, and Bassi, Roberto

Subjects
Carotenoids -- Spectra, Photosystem I -- Research, Adsorption -- Research, Biological sciences, Chemistry
Abstract

The spectroscopic characteristics of carotenoids associated with the antenna complexes of Photosystem I is studied. It is suggested that in the Lhca2-Lhca3 heterodimeric complex energy equilibration is not complete at least on a fast time scale.

2. Quenching of chlorophyll triplet states by carotenoids in reconstituted Lhca4 subunit of peripheral light-harvesting complex of photosystem I

Author

Carbonera, Donatella, Agostini, Giancarlo, Morosinotto, Tomas, and Bassi, Roberto

Abstract

A study on triplet quenching, the major photoprotection mechanism in antenna proteins, is studied in the light-harvesting complex of photosystem I. The process was investigated at low temperature by means of optically detected magnetic resonance that is well suited for investigation of triplet states in photosynthetic systems.

3. Recombinant Lhca2 and Lhca3 subunits of the photosystem I antenna system

Author

Castelletti, Simona, Morosinotto, Tomas, Robert, Bruno, Caffarri, Stefano, Bassi, Roberto, and Croce, Roberta

Subjects

Abstract

Research demonstrates the biosynthesis of Arabidopsis thaliana recombinant photosystem I antenna complexes, Lhca2 and Lhca3, in Escherichia coli and reconstitution of the pigment-refolded protein complexes. Data reveal that the complexes can modulate the absorption/emission properties and red-shifted spectral characteristics of the native forms.
