Neutron Reflectometry Study of DNA-directed spatial assembly of photosynthetic light-harvesting proteins
One of the key challenges for artificial photosynthesis is to optimize the capacity for light-harvesting (LH). We have recently developed a new method for the assembly of LH complexes onto DNA. Structural DNA nanotechnology holds considerable potential in this regard because the programmability and fidelity of DNA base-pairing provides access to a large variety of available DNA structures The LH complexes have however not yet been organized into higher order assemblies, due to our limited ability to investigate LH spatial positioning in two- and eventually three-dimensions. We therefore propose to use Neutron Reflectometry (NR) to reveal the layered structure of designed DNA/LH complexes. The resultant data would enable further, more rational and informed designs of more complex LH/DNA assemblies.
