2024 Pórna - Abstract. Ds-DNA viruses package their DNA into a preformed protein shell (procapsid) during maturation. Bacteriophage phi29 requires an RNA (pRNA) to package its genomic DNA into the procapsid. We report here that the pRNA upper and lower loops are involved in RNA/RNA interactions. Mutation in only one loop results in inactive pRNAs.

The RNA hairpin models- RNA5 and RNA7, had Tm values of 81.5 °C and 74.4 °C respectively ( Table 1 ). The higher Tm value for RNA5 is most likely due to the higher … RNA nanotechnology is a term that refers to the design, fabrication and use of nanoparticles that are mainly composed of RNAs via bottom-up self-assembly. The packaging RNA (pRNA) of the bacteriophage phi29 DNA packaging motor has been developed into a nanodelivery platform. This protocol describes … Misfolding and associated loss of function are common problems in constructing fusion RNA complexes due to changes in energy landscape and the nearest-neighbor principle. Here we report the incorporation and application of the pRNA-3WJ motif of the phi29 DNA packaging motor into fusion RNA with cont … PrnA, a Zn2Cys6 activator with a unique DNA recognition mode, requires inducer for in vivo binding. 2002 Apr;44 (2):585-97. doi: 10.1046/j.1365-2958.2002.02939.x.

Prohead RNA (pRNA) is an essential component in the assembly and operation of the powerful bacteriophage ϕ 29 DNA packaging motor. The pRNA forms a multimeric ring via intermolecular base-pairing interactions between protomers that serves to guide the assembly of the ring ATPase that drives DNA packaging. Bacteriophage 29 (Phi29) packaging RNA (pRNA) is one of the key components in the viral DNA-packaging motor. It contains two functional domains facilitating the translocation of DNA into the viral capsid by interacting with other elements in the motor and promoting adenosine triphosphates hydrolysis.Polná leží na řece Šlapance, která do katastru vstupuje na jihu, před rybníkem Peklo se do ní vlévá z pravé strany Zhořský potok.
