Conformational analysis of nucleic acids revisited: Curves+ [PDF]

open access: goldNucleic Acids Research, 2009
We describe Curves+, a new nucleic acid conformational analysis program which is applicable to a wide range of nucleic acid structures, including those with up to four strands and with either canonical or modified bases and backbones. The program is algorithmically simpler and computationally much faster than the earlier Curves approach, although it ...

Methylation Effects on Nucleic Acid Conformations [PDF]

open access: green, 1978
Chemical modification of nucleic acids by alkylating agents continues to be extensively explored from the perspective of chemical mutagenesis and carcinogenesis. Largely through the pioneering in vitro and in vivo studies of Lawley (1961), Lawley and Brookes (1963), Singer (1972), and Reese and coworkers (1965), coupled with theoretical predictions of ...

Global Studies of Single-Stranded Nucleic Acid Conformation [PDF]

open access: bronzeBiophysical Journal, 2013
Unstructured regions of RNA molecules require flexibility to accomplish many biological tasks such as conformational switching and protein recognition. Due to its highly charged backbone, the flexibility of single-stranded RNA is influenced by counterions.

High intrinsic hydrolytic activity of cyanobacterial RNA polymerase compensates for the absence of transcription proofreading factors [PDF]

open access: yes, 2020
The vast majority of organisms possess transcription elongation factors, the functionally similar bacterial Gre and eukaryotic/archaeal TFIIS/TFS. Their main cellular functions are to proofread errors of transcription and to restart elongation via ...

Development of purification process for dual‐function recombinant human heavy‐chain ferritin by the investigation of genetic modification impact on conformation

open access: yesEngineering in Life Sciences, 2021
Ferritin is a promising drug delivery platform and has been functionalized through genetic modifications. This work has designed and expressed a dual‐functional engineered human heavy‐chain ferritin (HFn) with the inserted functional peptide PAS and RGDK

Solvent interactions stabilising nucleic acid conformers [PDF]

open access: yesNucleic Acids Research, 1989
The transition of oligonucleotides from the B to the A conformation has been studied by the use of simple geometric calculations aimed at finding possible hydration sites which could stabilize these conformations. The method involves the classification of equally spaced grid points, surrounding the oligonucleotide, into groups depending on whether a ...

Dependence of interferon induction on nucleic acid conformation. [PDF]

open access: greenProceedings of the National Academy of Sciences, 1976
UV and circular dichroism characteristics of duplex analogs belonging to the (A)n-(U)n and (I)n-(C)n series were determined to assign qualitatively the nature of conformational differences caused by 5-pyrimidine and c7 purine substitutions in such duplexes.

Nucleotides: Structure and Properties [PDF]

open access: yes, 2005
Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...
