由于科学技术的高速发展和电泳技术分离大分子的成功,人们开始认识了一类新的蛋白质,即高活性群蛋白质(HMG)。HMG是一系列酸性小蛋白质的聚集体,具有高度的流动性,反映了它们质量很小,相对分子量均在30000以下。然而,其他与非组织染色体关联的蛋白质的分子量比我们已熟悉的HMG要大得多,人们对现有HMG的重视 Due to the rapid development of science and technology and the successful separation of macromolecules by electrophoresis, people have come to know a new class of proteins, namely high activity group proteins (HMGs). HMG is a collection of small acidic proteins with a high degree of fluidity, reflecting their low mass and relative molecular weights below 30,000. However, the molecular weight of other proteins associated with non-tissue chromosomes is much greater than the HMG we are already familiar with, and attention is being given to existing HMGs
