Abstract
The photosynthetic unit of Rhodopseudomonas viridis contains a reaction centre (P960) and a light harvesting complex (B1015). Immune electron microscopy combined with image processing has allowed the central core of the photosynthetic unit to be identified as the reaction centre and the surrounding protein ring as the light harvesting complex. This light harvesting complex, subdivided into twelve subunits was shown to contain 24 bacteriochlorophyll b molecules. A model is presented which may account for the far red shift of the Qy absorption of the bacteriochlorophyll b molecules in vivo.
