Light harvesting antenna on an amyloid scaffold.
A pigment array has been constructed within a paracrystalline amyloid nanotube and Förster energy transfer along the nanotube surface has been demonstrated to self-assembled acceptor dyes.
متن کاملA seventh bacterial chlorophyll driving a large light-harvesting antenna
The discovery of new chlorophyllous pigments would provide greater understanding of the mechanisms and evolution of photosynthesis. Bacteriochlorophyll f has never been observed in nature, although this name was proposed ~40 years ago based on structurally related compounds. We constructed a bacteriochlorophyll f-accumulating mutant of the green sulfur bacterium Chlorobaculum limnaeum, which or...
متن کاملMicroscopic quantum coherence in a photosynthetic-light-harvesting antenna.
We briefly review the coherent quantum beats observed in recent two-dimensional electronic spectroscopy experiments in a photosynthetic-light-harvesting antenna. We emphasize that the decay of the quantum beats in these experiments is limited by ensemble averaging. The in vivo dynamics of energy transport depends upon the local fluctuations of a single photosynthetic complex during the energy t...
متن کاملArtificial light-harvesting antenna systems grafted on a carbohydrate platform.
An enantiopure α-D-glucopyranoside derivative has been used as a platform to prepare artificial antenna systems based on bodipy subunits. Efficient and ultrafast energy transfer (in the fs and ps time regimes) takes place in the multibodipy systems.
متن کاملLight-harvesting antenna function of phycoerythrin in prochlorococcus marinus
Prochlorococcus marinus strain CCMP 1375 is the sole prokaryote to possess phycoerythrin in addition to (divinyl-)chlorophyll a/b binding antenna complexes. Here we demonstrate, employing a spectrofluorimetric assay, that phycoerythrin serves a light-harvesting antenna function (transfers energy to chlorophylls).
