Streptomyces subtilisin inhibitor (SSI) is a protein characterized by both its potent inhibitory activity toward subtilisin and its structure, composed of two homologous subunits. It binds two molecules of subtilisin to form a tetrameric complex.Intermolecularly cross-linked subtilisin is expected to form a polymeric complex with SSI. This could provide a useful model of protein-protein associatin. Therefore, Preparation of fluorescence-labeled and cross-linked subtilisin was carried out.
链霉菌亚硫蛋白酶抑制剂(SSI)是一种蛋白质,具有对亚硫蛋白酶的强抑制活性,并且其结构由两个同源亚基组成。它能结合两个亚硫蛋白酶分子形成四聚体复合物。通过分子间交联的亚硫蛋白酶预计将与SSI形成聚合复合物。这可以提供一个有用的蛋白质-蛋白质结合模型。因此,进行了荧光标记和交联亚硫蛋白酶的制备。
