A recent crystallographic study of the photosynthetic reaction center from a purple bacterium has been reviewed. The three-dimensional structure has been elucidated in consequence of the first success in crystallization of membrane proteins and in crystallography of extremely large protein complex. The molecular mechanism of electron transport system in the primary step of photosynthesis has been revealed on the basis of the present structure. For this work, the Nobel prize for chemistry in 1988 was awarded to J.Deisenhofer, R.Huber and H.Michel.
