Φ6 has been studied as a model to understand how segmented RNA viruses package their genomes, its structure has been studied by scientists interested in lipid-containing bacteriophages, and it has been used as a model organism to test evolutionary theory such as Muller's ratchet. Phage Φ6 has … Zobraziť viac Φ6 (Phi 6) is the best-studied bacteriophage of the virus family Cystoviridae. It infects Pseudomonas bacteria (typically plant-pathogenic P. syringae). It has a three-part, segmented, double-stranded Zobraziť viac Φ6 typically attaches to the Type IV pilus of P. syringae with its attachment protein, P3. It is thought that the cell then retracts its pilus, pulling the … Zobraziť viac • Double-stranded RNA viruses Zobraziť viac 1. Detailed molecular description 2. Descriptions of tests of evolutionary theory by the Turner Lab 3. Descriptions of tests of evolutionary theory by the Burch Lab Zobraziť viac The genome of Φ6 codes for 12 proteins. P1 is a major capsid protein which is responsible of forming the skeleton of the polymerase complex. … Zobraziť viac RNA-dependent RNA polymerases (RdRPs) are critical components in the life cycle of double-stranded RNA (dsRNA) viruses. However, it is not … Zobraziť viac Web17. feb 2010 · In the case of Φ6, we have shown that polymerase is inactive during the packaging of the plus-strand transcripts of the genome until all three are inside the core ( 3 ). According to the working model, the expansion of the core changes the conformation of the polymerase so as to turn it on.

Web27. mar 2024 · The carboxyl-terminal repeat domain (CTD) of RNA polymerase II is thought to help coordinate events during RNA metabolism. The mammalian CTD consists of 52 imperfectly repeated heptads followed by 10 additional residues at the C terminus. The CTD is required for cleavage and polyadenylation in vitro. We studied poly(A)-dependent … Web1. nov 2024 · The phi6 RdRp is produced as a recombinant protein, purified to homogeneity and used for in vitro synthesis of dsRNA. The enzyme has high processivity and low template specificity which enables efficient production of dsRNAs from a wide variety of heterologous ssRNA templates [35], [36]. gear tilt positioner
