RNA拓扑重塑病毒静电稳定性

RNA topology remolds electrostatic stabilization of viruses

摘要:

简单的RNA病毒有效地将其基因组封装到纳米大小的蛋白质外壳中:衣壳。基因组和衣壳蛋白的自发共组装主要由带负电荷的RNA和带正电荷的内衣壳壁之间的静电相互作用驱动。使用场论公式,我们表明,固有的分支RNA二级结构允许病毒最大限度地提高封装的基因组的量,使组装更有效,允许病毒RNA在感染的宿主细胞中复制过程中竞争细胞RNA。

英文摘要:

Simple RNA viruses efficiently encapsulate their genome into a nano-sized protein shell: the capsid. Spontaneous co-assembly of the genome and the capsid proteins is driven predominantly by electrostatic interactions between the negatively charged RNA and the positively charged inner capsid wall. Using field theoretic formulation we show that the inherently branched RNA secondary structure allows viruses to maximize the amount of encapsulated genome and make assembly more efficient, allowing viral RNAs to out-compete cellular RNAs during replication in infected host cells.
