Rdrp activity regulation
Did you know?
WebRNA-dependent RNA polymerases (RdRPs) encoded by RNA viruses represent a unique class of processive nucleic acid polymerases, carrying out DNA-independent replication/transcription processes. Although viral RdRPs have versatile global structures, they do share a structurally highly conserved active site comprising catalytic motifs A-G. 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.

WebRdRP could synthesize antisense transcripts from aberrant sense RNAs, leading to the production of dsRNA that triggers PTGS through a mechanism that possibly involves further RdRP activity (26, 29) . Intriguingly, qde1 and RdRP homologs have been found in a number of plants, including Arabidopsis , as well as in C. elegans and fission yeast ... chino valley az to williams azWebThe 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). granny mac bubble hashWebFeb 15, 2024 · The compounds were in vitro evaluated for HCV RdRp inhibitory activity using Ava5 cells (cell with HCV replicon).
