The PufX protein is an important component of the reaction centre–light-harvesting 1 (RC–LH1) complex of Rhodobacter species of purple photosynthetic bacteria. Early studies showed that removal of the PufX protein causes changes in the structure of the RC–LH1 complex that result in a loss of the capacity for photosynthetic growth, and that this loss can be overcome though furthermutations that change the structure of theLH1 antenna. More recent studies have examined interactions of the PufX protein with other components of the RC–LH1 complex. This reviewconsiders our current understanding of the structure and function of the PufX protein, how this protein interacts with other components of the photosyntheticmembrane, and its influence on the oligomeric state of the RC–LH1 complex and the larger-scale architecture of the photosynthetic membrane.
