Abstract
Bacteriochlorophyll (Bchl) is distributed in two fractions, quite distinct functionally. A small fraction, about 3% of the total, forms part of the photoreaction center (RC), which carries out the photochemical reaction. The rest of the Bchl belongs to the light harvesting (LH) antenna, which absorbs radiant energy and transfers it to the RC. In any case, Bchl is always com-plexed to proteins and other pigments. Two types of LH complexes have been described in purple bacteria, B870 and B800–850, their designation referring to the approximate maxima in the near infrared (NIR) absorption spectrum (for a revision see Cogdell and Thornber 1980). All purple species studied so far contain complexes of the two types, except Rhodospirillum rubrum which possesses only the B870 class.
