Basic 7S globulin, a cysteine-rich protein from soybean seeds, consists of subunits containing 27 kD and 16 kD chains linked by disulfide bonding. Three differently sized subunits of the basic 7S globulin were detected and partially separated by SP Sepharose chromatography. The basic 7S globulin was characterized as a member of a superfamily of structurally related but functionally distinct proteins descended from a specific group of plant aspartic proteinases.
碱性7S球蛋白是一种来自大豆种子的富含半胱氨酸的蛋白质，由通过二硫键连接的含有27 kD和16 kD链的亚基组成。通过SP Sepharose色谱法检测并部分分离出了三种不同大小的碱性7S球蛋白亚基。碱性7S球蛋白被鉴定为一个结构相关但功能不同的蛋白质超家族的成员，该超家族起源于一组特定的植物天冬氨酸蛋白酶。
