[[https://www.uniprot.org/uniprot/RDRP_REOVD RDRP_REOVD]] RNA-directed RNA polymerase that is involved in transcription and genome replication. Following infection, it catalyzes the synthesis of fully conservative plus strands. After core assembly, which consists in recruitment of one capped plus-strand for each genomic segments and polymerase complexes, the polymerase switches mode and catalyzes the synthesis of complementary minus-strands.
-
The reovirus polymerase and those of other dsRNA viruses function within the confines of a protein capsid to transcribe the tightly packed dsRNA genome segments. The crystal structure of the reovirus polymerase, lambda3, determined at 2.5 A resolution, shows a fingers-palm-thumb core, similar to those of other viral polymerases, surrounded by major N- and C-terminal elaborations, which create a cage-like structure, with four channels leading to the catalytic site. This "caged" polymerase has allowed us to visualize the results of several rounds of RNA polymerization directly in the crystals. A 5' cap binding site on the surface of lambda3 suggests a template retention mechanism by which attachment of the 5' end of the plus-sense strand facilitates insertion of the 3' end of the minus-sense strand into the template channel.
