抽象的
呼吸综合病毒(RSV)大蛋白L是RNA依赖性RNA聚合酶复合物的催化亚基。当前,RSV L. RSV的L蛋白的序列比对尚无RSV的结构信息,揭示了存在两个可变区域VR1和VR2的存在。在与Morbillivirus和Rhabdovirus L基因进行比较之后,位于域V和VI之间的VR2被选为编码表位标签HA或荧光蛋白EGFP和MCHERRY的序列的插入位点。重组标记的L蛋白与转染细胞中的RSV N和P蛋白共定位。这些重组聚合酶使用病毒微型系统测定法显示出功能性,与未修饰的L聚合酶相比,它们的活性降低了约70%。我们还通过位置定向诱变表明,GDNQ基序(对于HRSV的长应变为810-813)对于L活性至关重要。
