The reaction centre (RC) of green sulphur bacteria is a FeS-type RC, as are the RCs of Photosystems I (PS I) of oxygenic photosynthetic organisms and of heliobacteria. The core domains of both green sulphur bacterial and heliobacterial RCs are considered to be homodimeric, in contrast to those of purple bacteria, PS I and Photosystem II (PS II). This paper briefly describes the techniques of electron microscopy and image processing suited to investigate the structure of these proteins. Recent advances in the study of the structure of the green sulphur bacterial RC, primarily achieved by the application of scanning transmission electron microscopy, are reviewed.
