Data for Photosynthetic pigment-protein complexes as highly-connected networks : implications for robust energy transport Scott Habershon (1263891) Lewis A. Baker (3975887) Photosynthesis -- Industrial applications Photosynthetic bacteria Quantum theory Migrated from ePrints Photosynthetic pigment-protein complexes (PPCs) are a vital component of the light-harvesting machinery of all plants and photosynthesising bacteria, enabling efficient transport of the energy of absorbed light towards the reaction centre, where chemical energy storage is initiated. PPCs comprise a set of chromophore molecules, typically bacteriochlorophyll species, held in a well-defined arrangement by a protein scaffold; this relatively rigid distribution leads to a viewpoint in which the chromophore subsystem is treated as a network, where chromophores represent vertices and inter-chromophore electronic couplings represent edges. This graph-based view can then be used as a framework within which to interrogate the role of structural and electronic organization in PPCs. Here, we use this network-based viewpoint to compare EET dynamics in the light-harvesting complex II (LHC-II) system commonly found in higher plants and the Fenna-Matthews-Olson (FMO) complex found in green sulfur bacteria. The results of our simple network-based investigations clearly demonstrate the role of network connectivity and multiple EET pathways on the efficient and robust EET dynamics in these PPCs, and highlight a role for such considerations in the development of new artificial light-harvesting systems.<br><br>Simulation results from Figures 4-9 in submitted article. 2026-09-14T11:49:44Z Dataset Dataset 10.82444/warw.33734407.v1 https://figshare.com/articles/dataset/Data_for_Photosynthetic_pigment-protein_complexes_as_highly-connected_networks_implications_for_robust_energy_transport/33734407 CC BY 4.0
