== Publication Abstract from PubMed ==
Rice bifunctional alpha-amylase/subtilisin inhibitor (RASI) can inhibit both alpha-amylase from larvae of the red flour beetle (Tribolium castaneum) and subtilisin from Bacillus subtilis. The synthesis of RASI is up-regulated during the late milky stage in developing seeds. The 8.9 kDa molecular-weight RASI from rice has been crystallized using the hanging-drop vapour-diffusion method. According to 1.81 angstroms resolution X-ray diffraction data from rice RASI crystals, the crystal belongs to space group P2(1)2(1)2, with unit-cell parameters a = 79.99, b = 62.95, c = 66.70 angstroms. Preliminary analysis indicates two RASI molecules in an asymmetric unit with a solvent content of 44%.
