Abstract
From the thermoacidophilic archaebacterium, Thermoplasma acidophilum, a proteolytically active particle has been isolated which is almost identical in size and shape with the multicatalytic proteinase (prosome) from rat. This result indicates that prosomes have been developed early in evolution and that they possibly serve functions common to all living cells.
摘要
从嗜热嗜酸古细菌嗜酸热原体中分离出一种蛋白水解活性颗粒，其大小和形状与大鼠的多催化蛋白酶（蛋白酶体）几乎相同。这一结果表明蛋白酶体在进化早期就已形成，并且它们可能具有所有活细胞共有的功能。
