“…The relative positions and orientations of Bchl sites 1 to 7 are remarkably well-conserved across GSB species, 36,43 despite differences in the amino acid sequence in the surrounding FMO protein environment; 15 furthermore, the dominant spectral characteristics of FMO complexes from different species are similarly well-conserved, falling into one of two classes which only differ due to different orientations of Bchl 8. 15 Given the conserved nature of the FMO complex in GSB, it is tempting to ask whether this particular PPC motif is in any way optimised for its EET functionality.…”

“…In contrast, far less emphasis has been placed on answering a more fundamental question: why are PPCs built the way they are? Given the evolutionary time scales and the pressures of natural selection, 14,15 it is tempting to ask whether PPCs are specifically optimised for their role in the photosynthetic process or whether factors external to the EET process, such as synthetic accessibility or robustness to thermal fluctuations, are instead responsible for ultimately shaping the molecular organisation of PPCs. Answering such questions would, in turn, lead to a better understanding of how to construct improved artificial photosynthetic systems for water splitting, 16,17 or more efficient light-harvesting materials for solar energy technologies.…”

“…Much attention has been focused on the emergence of oxygenic photosynthesis, as this likely had far-reaching implications for life on Earth (Olson and Blankenship, 2004, Xiong, 2006, Blankenship, 2010. 16S rRNA phylogeny reveals a patchy picture of bioenergetic pathways in different taxonomic groups, suggestive of rampant horizontal gene transfer (HGT) (Castresana, 2001, Reysenbach and Shock, 2002, Boucher et al, 2003, Koumandou and Kossida, 2014.…”

“…New data does suggest that the last universal common ancestor of all cells (LUCA) was an hydrogen-dependent autotroph using carbon dioxide as the ultimate electron acceptor, relying on iron-sulphur clusters for catalysis that may have originated in a hydrothermal setting [32]; gene ontology is suggesting that the earliest life was indeed metabolismdriven [33]. It is also thought that the earliest photosynthetic organisms were anoxygenic, but electron transport was fundamental to the process [34]. Thus efficient electron transport may well be a key component of life.…”
