#=GF CC   A photosynthetic reaction-centre complex is found in certain
#=GF CC   green sulphur bacteria such as Chlorobium vibrioforme which are
#=GF CC   anaerobic photo-auto-trophic organisms. The primary electron
#=GF CC   donor is P840, a probable B-Chl a dimer, and the primary
#=GF CC   electron acceptor is a B-Chl monomer. Also on the donor side
#=GF CC   c-type cytochromes are known to function as electron donors to
#=GF CC   photo-oxidised P840. This family is thus the secondary
#=GF CC   endogenous donor of the photosynthetic reaction-centre complex
#=GF CC   and is a membrane-bound cytochrome containing a single haem
#=GF CC   group.
