  • n. A photosynthetic antenna complex found in green sulfur bacteria and some green filamentous anoxygenic phototrophs, differing from other antenna complexes by its large size and lack of protein matrix supporting the photosynthetic pigments.

  • Specifically, the team examined the protein scaffold connecting the bacteria's external solar collectors, called the chlorosome, to reaction centers deep inside the cells.

  • To get around this problem, the team used a combination of techniques to study the chlorosome.

  • The team then went a step further and used solid-state NMR spectroscopy — a technique in which samples are spun very rapidly and exposed to a magnetic field — to look deep inside the chlorosome.

  • “Each chlorosome in a green bacterium has a unique organization,” said Bryant.

  • If all of the chlorophylls are identically arranged in a chlorosome, then the energy from the photon, once it is absorbed, is going to wander around over all of those chlorophylls, which could take a long time.

  • “At first it seems counterintuitive that green bacteria have managed to evolve a better light-harvesting system by increasing disorder in the chlorosome structure,” said Bryant.

  • They used genetic techniques to create a mutant bacterium with a more regular internal structure, cryo-electron microscopy to identify the larger distance constraints for the chlorosome, solid-state nuclear magnetic resonance (NMR) spectroscopy to determine the structure of the chlorosome's component chlorophyll molecules, and modeling to bring together all of the pieces and create a final picture of the chlorosome.
