Structure of the water-soluble Fenna–Matthews–Olsen protein complex (FMO) from Prosthecochloris aestuarii at 1.3 Å resolution, PDB entry 3EOJ [104]. (A) Top view of the trimer with regard to the bacterial membrane plane, seen from the cytoplasm/chlorosome. (B) Side view of a single monomer with regard to the bacterial membrane plane. The protein backbone is shown in grey. Bacteriochlorophyll a is shown in blue.
