Codon usage and secondary structure of MS2 phage RNA.
MS2 is an RNA bacteriophage (3569 bases). The secondary structure of the RNA has been determined, and is known to play an important role in regulating translation. Paired regions of the genome have a higher G+C content than unpaired regions. It has been suggested that this reflects selection for high G+C content to encourage pairing, but a re-analysis of the data together with computer simulati...
متن کاملBipartite modular structure of intrinsic, RNA hairpin-independent termination signal for phage RNA polymerases.
The phage SP6 RNA and T7 RNA polymerases, which are closely related to each other, intrinsically stop at two signals in the Escherichia coli rrnB terminator t1 through different mechanisms. The downstream signal functioned without an RNA secondary structure formation, in which the signal was still active when separated from the upstream, hairpin-forming signal, and IMP incorporation enhanced it...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولConstraint-Based Strategy for Pairwise RNA Secondary Structure Prediction
Context: RNA secondary structure prediction depends on the situation: when only a few (sometimes putative) RNA homologs are available, one of the most famous approach is based on a set of recursions proposed by Sankoff in 1985. Although this modus operandi insures an algorithmically optimal result, the main drawback lies in its prohibitive time and space complexities. A series of heuristics wer...
متن کاملAltered 3'-terminal RNA structure in phage Qbeta adapted to host factor-less Escherichia coli.
The RNA phage Qbeta requires for the replication of its genome an RNA binding protein called Qbeta host factor or Hfq protein. Our previous results suggested that this protein mediates the access of replicase to the 3'-end of the Qbeta plus strand RNA. Here we report the results of an evolutionary experiment in which phage Qbeta was adapted to an Escherichia coli Q13 host strain with an inactiv...
