1D7E - PubMed Abstract: 
The conformational changes during the photocycle of the photoactive yellow protein have been the subject of many recent studies. Spectroscopic measurements have shown that the photocycle also occurs in a crystalline environment, and this has been the basis for subsequent Laue diffraction and cryocrystallographic studies ...
