Proteins are the workers in cells; they carry out designated cellular functions tirelessly throughout their lifetimes. Some proteins can even hold two different jobs. One example of a dual-duty protein is the bacterial photosynthetic core complex. The photosyntehtic core complex performs the first steps of photosynthesis: absorption of sunlight and processing of light energy. Besides providing solar power, the core complex acts as an architect of the cell by shaping membranes in the interior of photosynthetic bacteria. Combining computational modeling and electron microscopy data using the Molecular Dynamics Flexible Fitting method, computational biologists have recently reported studies of both functions of the core complex, namely, the light-absorbing features and the membrane-sculpting properties.
