Computer Model Offers New Insight On Bacterial Photosynthesis

Researchers at the University of Illinois used advanced computer modeling to study the purple bacteria Rhodobacter sphaeroides. The team created a three-dimensional model depicting how the light-harvesting complexes aggregate in a ring around the photosynthetic reaction center, shedding light on efficient energy capture. This breakthro...
