Abstract
This work continues the series of our studies on the basic principles in the organization of natural light-harvesting antennae, which we theoretically predicted for the optimal model light-harvesting systems, initiated by our concept of the rigorous optimization of photosynthetic apparatus structure by functional criteria. This work deals with the problem of the structure optimization of Cf.aurantiacus heterogeneous superantenna, consisting of several uniform subantennae, which raises the problem of their optimal interfacing. Mathematical modeling of the functioning of this natural superantenna allowed us to consider possible optimization of this process via optimizing the mutual orientation of Q y transition dipole moments vectors of the light-harvesting molecules in adjacent subantennae and, as a consequence, to suggest a model of optimal orientation of B798 BChl a Q y transition dipoles within a single chlorosome. This model was confirmed by polarized difference absorption spectroscopy of isolated Cf.aurantiacus chlorosomes.
