Hello Everyone,
This Friday Jenny will be presenting group meeting at the usual time
and place (2pm, Division Room). Her talk is entitled "An atomistic,
molecular and working view of the green sulfur bacteria’s light
harvesting equipment". An abstract can be found below:
Green sulfur bacteria (or chlorobaculum tepidum) is much admired (for
some ad nauseam) for its ability to use efficiently in anaerobic
photosynthesis the little light it encounters at 100 m below water
level. As experimental discoveries are ubiquitously being made
towards the structure of the equipment with which the bacteria harness
and transfer this energy there is opportunity for theoretical models
to also progress with this new information. We look at how classical
(based on ab initio parameters for novel ‘ligands’) molecular dynamics
(MD) can shed light on the construction and workings of this
equipment. This is a top to bottom approach to see how MD can be
useful towards understanding the progression of exciton dynamics in
order to construct a full pathway from chlorosome to reaction centre,
that either impersonates or improves upon that efficiency observed in
nature.
