Benchmarking Calculations of Excitonic Couplings between Bacteriochlorophylls.
Excitonic couplings between (bacterio)chlorophyll molecules are necessary for simulating energy transport in photosynthetic complexes. Many techniques for calculating the couplings are in use, from the simple (but inaccurate) point-dipole approximation to fully quantum-chemical methods. We compared several approximations to determine their range of applicability, noting that the propagation of ...
متن کاملElectronic Excitations in Aggregates of Bacteriochlorophylls
Photosynthetic organisms have developed antenna systems to enlarge their cross section for capturing sunlight. These systems involve in some cases aggregates of bacteriochlorophylls (BChls). The structure of one such aggregate, a tightly coupled circular hexadecamer of BChls and a loosely coupled octamer of BChls, has recently been solved. In this paper we investigate the electronic excitations...

متن کاملAlternating syn-anti bacteriochlorophylls form concentric helical nanotubes in chlorosomes.
Chlorosomes are the largest and most efficient light-harvesting antennae found in nature, and they are constructed from hundreds of thousands of self-assembled bacteriochlorophyll (BChl) c, d, or e pigments. Because they form very large and compositionally heterogeneous organelles, they had been the only photosynthetic antenna system for which no detailed structural information was available. I...

I. Substrate specificity of POR Several modified Pchlid derivatives were tested for substrate activity with POR (Griffiths, 1991; Helfrich, 1995; Helfrich et al., 1996; Schoch et al., 1995; Klement et al., 1999). The central Mg can be substituted by Zn while the metal-free Pchlid and the Ni, Co, and Cu complex are inactive. Modifications of the side chains at rings A and B are throughout tolera...
