WebJun 29, 2011 · Thus, although RdRP activity is ubiquitous in eukaryotes, it need not be a general requirement for transposon control. Concluding, our models show that the control of transposon activity can be achieved by alternative pathways that lack RdRP and act through different feedback mechanisms. WebApr 28, 2024 · The catalytic subunit of SARS-CoV-2 RNA-dependent RNA polymerase (RdRp), Nsp12, has a unique NiRAN domain that transfers nucleoside monophosphates to the Nsp9 protein. The NiRAN and RdRp modules form a dynamic interface distant from their catalytic sites and both activities are essential for viral replication. We report that codon-optimized …

Although viral RdRPs have versatile global structures, they do share a structurally highly conserved active site comprising catalytic motifs A-G.
WebThe P123 polyprotein, in itself, lacks any intrinsic RNA synthetic activity as the RNA-dependent RNA polymerase (RdRp; the nsP4 protein) is absent. Similarly, the P1234 form of the polyprotein is incapable of RNA synthesis until proteolytic processing releases the nsP4 component of the polyprotein (Shirako & Strauss, 1994).
