antaRNA – Multi-objective inverse folding of pseudoknot RNA using ant-colony optimization

open access: yesBMC Bioinformatics, 2015
Many functional RNA molecules fold into pseudoknot structures, which are often essential for the formation of an RNA’s 3D structure. Currently the design of RNA molecules, which fold into a specific structure (known as RNA inverse folding) within ...

Free Energy Landscape and Multiple Folding Pathways of an H-Type RNA Pseudoknot

open access: yesPLoS ONE, 2015
How RNA sequences fold to specific tertiary structures is one of the key problems for understanding their dynamics and functions. Here, we study the folding process of an H-type RNA pseudoknot by performing a large-scale all-atom MD simulation and bias ...

Nanopore electric snapshots of an RNA tertiary folding pathway

open access: yesNature Communications, 2017
While RNA folding is critical for its function, study of this process is challenging. Here, the authors combine nanopore single-molecule manipulation with theoretical analysis to follow the folding of an RNA pseudoknot, monitoring the intermediate states

ENTRNA: a framework to predict RNA foldability

open access: yesBMC Bioinformatics, 2019
Background RNA molecules play many crucial roles in living systems. The spatial complexity that exists in RNA structures determines their cellular functions.

Partitioning RNAs into pseudonotted and pseudoknot-free regions modeled as Dual Graphs [PDF]

open access: yesarXiv, 2016
Dual graphs have been applied to model RNA secondary structures. The purpose of the paper is two-fold: we present new graph-theoretic properties of dual graphs to validate the further analysis and classification of RNAs using these topological representations; we also present a linear-time algorithm to partition dual graphs into topological components ...

Frameshifting RNA pseudoknots: Structure and mechanism

open access: yesVirus Research, 2009
Programmed ribosomal frameshifting (PRF) is one of the multiple translational recoding processes that fundamentally alters triplet decoding of the messenger RNA by the elongating ribosome. The ability of the ribosome to change translational reading frames in the -1 direction (-1 PRF) is employed by many positive strand RNA viruses, including ...

An efficient simulated annealing algorithm for the RNA secondary structure prediction with Pseudoknots

open access: yesBMC Genomics, 2019
Background RNA pseudoknot structures play an important role in biological processes. However, existing RNA secondary structure prediction algorithms cannot predict the pseudoknot structure efficiently.

The Influenza A PB1-F2 and N40 Start Codons Are Contained within an RNA Pseudoknot.

open access: yesBiochemistry, 2015
Influenza A is a negative-sense RNA virus with an eight-segment genome. Some segments encode more than one polypeptide product, but how the virus accesses alternate internal open reading frames (ORFs) is not completely understood. In segment 2, ribosomal

Curli synthesis and biofilm formation in enteric bacteria are controlled by a dynamic small RNA module made up of a pseudoknot assisted by an RNA chaperone

open access: yesNucleic Acids Research, 2014
RydC pseudoknot aided by Hfq is a dynamic regulatory module. We report that RydC reduces expression of curli-specific gene D transcription factor required for adhesion and biofilm production in enterobacteria.
