Abstract: The study on the interaction between protein target and little molecules can help design new drugs, which have more selective and higher activities. A large number of inhibitors,including ureas, triazines and phenols etc.,are known to block photosystem Ⅱ by displacing plastoquinone from the QB-binding niche of the D1 protein in the reaction center. The X-ray crystall structure of D1 protein in high plant is unknown, but the X-ray crystal structure of L protein of photosynthetic reaction centre of Rps. Viridis has already proved in 80'. Based on this structure, the 3D-structure of Pisnm Saihmm 32Kdal (Dl) was constructed by homology modeling method, and the properties, such as steric, hydrophobic, electrostatic properties of active sites region of the Dl protein were also characterized by Grid Search method with probes of CH3E, H2O, NT and proton.The detail proposal of the model will be shown elsewhere.
