An in vitro comparison was made of the RNA polymerase activity associated with Newcastle disease virus (NDVo) and three clones of the temperature-sensitive mutant (NDVpi) isolated from persistently infected L cells. Less polymerase activity was associated with the NDVpi clones. Also, compared to NDVo, an increase in incubation temperature from 32 to 37 or 42 C resulted in a marked decrease in polymerase activity for the temperature-sensitive mutants which coincided with their inability to replicate at 42 C.
对与新城疫病毒(NDVo)以及从持续感染的L细胞中分离出的温度敏感突变体的三个克隆(NDVpi)相关的RNA聚合酶活性进行了体外比较。NDVpi克隆的聚合酶活性较低。此外,与NDVo相比,将孵育温度从32℃提高到37℃或42℃会导致温度敏感突变体的聚合酶活性显著降低,这与它们在42℃下无法复制相一致。
