Summary

The structure of the LH2 complex from Rps. acidophila is presented, with special emphasis on the detailed arrangement of the pigments (BChl a and the carotenoid, rhodopin-glucoside). The BChl a/s are arranged into two distinct groups, 9 monomeric ones absorbing at 800 nm at 18 tightly coupled ones absorbing of ∼860 nm. The carotenoids connect these two groups of BChl a/s. Recent fs and ps time-resolved energy transfer experiments, designed to probe the mechanism of carotenoid to BCh1 a, singlet-singlet energy transfer in LH2 are described. Possible mechanisms of these energy transfer events are discussed.
