The Fenna-Matthews-Olson Complex (FMO) of Prosteochloris aestuarii was the first antenna complex to have its structure determined by x-ray crystallography and servs as an energy funnel from the chlorosome to the reaction center. Using atomistic quantum dynamical simulation of energy transfer between pigments using Time Dependent Density Functional Tight Binding we have determined that the protein effects the energy flow patway regulating coherence in order to achieve better efficiency of the energy transfer process.
