从电子显微照片中,α2-巨球蛋白的“闭合”形式、“开放”形式和胰酶复合体的单分子被计算机计算出平均值。对分子图像进行了讨论。电泳性快速迁移的“F”型分子具有“闭合”型。在α2-巨球蛋白/胰蛋白酶复合体的情况下,两个附着的胰酶分子彼此非常接近,并且位于α2-巨球蛋白分子的中心部分。
From electron micrographs single molecules of alpha 2-macroglobulin in the "closed" form, the "open" form and as the trypsin complex have been computer averaged. The molecular images are discussed. Molecules of the electrophoretically fast migrating "F-form" have the "closed" form. In the case of the alpha 2-macroglobulin/trypsin complex the two attached trypsin molecules are located very near to each other and in the central part of the alpha 2-macroglobulin molecule.
