**6. Basic 7S globulin (Bg7S)**

Basic 7S globulin (Bg7S) is expressed by soybeans in response to biotic or abiotic stress. It is capable of binding to a 4-kDa protein involved in cell proliferation. Bg7S is detected in le‐ gumes, and other plants. However, its function has not been elucidated. Bg7S has been suc‐ cessfully crystallized. Orthorhombic and monoclinic crystals were procured under various

conditions and belonged to space groups P2(1)2(1)2, with unit-cell parameters a = 111.9, b = 130.1, c = 287.8 Å, and P2(1), with unit-cell parameters a = 85.3, b = 137.6, c = 162.1 Å, β = 91.2°, respectively [8].
