Abstract

An 11S protein component obtained from specific dissociation of bacteriophage f(2) underwent a change in the state of association when dialyzed to pH 4. At low temperatures a dissociation to 5.5S subunits was observed, while at 24 degrees to 34 degrees C a 37S particle was formed. The latter particles have properties which closely resemble those expected for the RNA-free viral capsid.

摘要

从噬菌体f(2)的特异性解离中获得的一种11S蛋白质组分，在透析至pH 4时会发生缔合状态的变化。在低温下观察到它解离为5.5S亚基，而在24℃至34℃时会形成37S颗粒。后者颗粒的性质与无RNA病毒衣壳预期的性质非常相似。
