== Publication Abstract from PubMed ==
Bowman-Birk inhibitors (BBIs) are cysteine-rich proteins with inhibitory activity against proteases that are widely distributed in monocot and dicot species. The expression of rice BBI from Oryza sativa is up-regulated and induced by pathogens or insects during germination of rice seeds. The rice BBI (RBTI) of molecular weight 15 kDa has been crystallized using the hanging-drop vapour-diffusion method. According to the diffraction of rice BBI crystals at a resolution of 2.07 A, the unit cell belongs to space group P2(1)2(1)2(1), with unit-cell parameters a = 74.37, b = 96.69, c = 100.36 A. Preliminary analysis indicates four BBI molecules in an asymmetric unit, with a solvent content of 58.29%.
