MetaCyc Compound: bacteriochlorophyll c

Superclasses: a macrocycle a chlorin a bacteriochlorin
an organometallic compound

Summary:
bacteriochlorophyll c is found in the chlorosomes of certain bacteria, such as Chlorobium limicola. Chlorosomes are very large light-harvesting organelles (~1,500 bacteriochlorophyll molecules per reaction center), found only in green sulfur bacteria and green filamentous bacteria. Based on electron microscopic observations, chlorosomes are filled with 10-30 rod-shaped elements which are oriented parallel to the long axis of the chlorosomes and have a diameter of 10 nm. According to the present model, each rod consists of a tubular bilayer formed by self-organization of the antenna bacteriochlorophyll molecules. Unlike all other known photosynthetic antenna, in which the chlorophyll molecules are bound to proteins, chlorosomes do not contain accessory proteins.

bacteriochlorophyll c molecules from Chlorobium limicola were shown to form piggyback-dimer-based parallel layers within the chlorosomes [Egawa07].

The R groups in the structure can be either methyl groups or hydrogen atoms.
