The structure and function of CP47 and CP43 in Photosystem II

This Minireview presents a summary of recent investigations examining the structure and functions of the Photosystem II chlorophyll-proteins CP47 and CP43, updating our previous review which appeared in 1990 (TM Bricker, Photosynth Res 24: 1-13). Since this time, numerous studies have clarified the roles of these chlorophyll-proteins within the photosystem. Biochemical, molecular and structural studies (electron and X-ray diffraction) have demonstrated the close association of these components with the photochemical reaction center of the photosystem and with the extrinsic oxygen evolution enhancer proteins.
