RNA polymerase activity was assayed in different particle classes of Penicillium stoloniferum virus S. RNA polymerase activity was found to be associated with H particles, which contain double-stranded RNA and single-stranded RNA, but not with L particles, which contain only double-stranded RNA and not with M particles, which contain only single-stranded RNA. In H particles the reaction occurred with the formation of one new molecule of double-stranded RNA (or two complementary single strands of RNA) per virus particle and the production of product particles (P particles), which contained two molecules of double-stranded RNA (or its equivalent). This RNA polymerase is therefore a replicase, which catalyses the synthesis of the two complementary strands of double-stranded RNA in a single virus particle. This is the first report of this type of RNA polymerase system.
对匐枝青霉病毒S的不同颗粒类型进行了RNA聚合酶活性测定。发现RNA聚合酶活性与含有双链RNA和单链RNA的H颗粒相关,而与仅含有双链RNA的L颗粒以及仅含有单链RNA的M颗粒无关。在H颗粒中,反应发生时每个病毒颗粒形成一个新的双链RNA分子(或两条互补的单链RNA),并产生含有两个双链RNA分子(或其等效物)的产物颗粒(P颗粒)。因此,这种RNA聚合酶是一种复制酶,它催化单个病毒颗粒中双链RNA的两条互补链的合成。这是关于这种类型RNA聚合酶系统的首次报道。
