[A discrepancy between the experimental and theoretical data on energy migration from B800 to B850 in LH-2 antennary complexes in purple bacteria]

Biofizika 2004, 49 (4): 653-8
A discrepancy between the times of excitation transfer from B800 to B850 bacteriochlorophyll fractions in LH-2 complexes of purple bacteria was revealed. The experimental value (0.7-0.8 ps from literature sources) are at least four times lower than that (> 3.2 ps) calculated theoretically on the basis of recently obtained atomic structure of LH2. Possible reasons for this discrepancy are discussed.
