Nontransmissible (exvectorial) isolates of wound tumor virus retain the ability to catalyze in vitro synthesis of RNA. Furthermore, exvectorial virus particles exhibit mRNA-2'-O-methyltransferase activity even after long-term (30-year) passage in a host that lacks this enzyme activity.
伤口肿瘤病毒的非传播性(非媒介传播)分离株保留了在体外催化RNA合成的能力。此外,即使在缺乏这种酶活性的宿主中长期(30年)传代后,非媒介传播的病毒颗粒仍表现出mRNA-2'-O-甲基转移酶活性。
