Louse (Insecta : Phthiraptera) mitochondrial 12S rRNA secondary structure is highly variable [PDF]

open access: yes, 2002
Lice are ectoparasitic insects hosted by birds and mammals. Mitochondrial 12S rRNA sequences obtained from lice show considerable length variation and are very difficult to align.

Kinetic Target‐Guided Synthesis of Small‐Molecule G‐Quadruplex Stabilizers

open access: yesChemistryOpen, 2020
The formation of a G‐quadruplex motif in the promoter region of the c‐MYC protooncogene prevents its expression. Accordingly, G‐quadruplex stabilization by a suitable ligand may be a viable approach for anticancer therapy.

Modelling DNA and RNA secondary structures using matrix insertion–deletion systems

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2016
Insertion and deletion are operations that occur commonly in DNA processing and RNA editing. Since biological macromolecules can be viewed as symbols, gene sequences can be represented as strings and structures can be interpreted as languages.

The predicted secondary structure of enolase [PDF]

open access: yesBiochemical Journal, 1986
The results of several secondary-structure prediction programs were combined to produce an estimate of the regions of alpha-helix, beta-sheet and reverse turn for both chicken skeletal-muscle and yeast enolase sequences. The predicted secondary-structure content of the chicken enzyme is 27% alpha-helix and less than 10% beta-sheet, whereas in the yeast

Tribochemical Interaction of Multicomponent Aluminum Alloys During Sliding Friction with Steel

open access: yesLubricants, 2020
In this work, aluminum multicomponent alloys were studied after friction with steel in a mixed lubrication regime. The resulting secondary structures on the friction surface were investigated by scanning electron microscopy (SEM), energy dispersive ...

Secondary structures in RNA synthesis, splicing and translation

open access: yesComputational and Structural Biotechnology Journal, 2022
Even though the functional role of mRNA molecules is primarily decided by the nucleotide sequence, several properties are determined by secondary structure conformations. Examples of secondary structures include long range interactions, hairpins, R-loops

Linkers of secondary structures in proteins [PDF]

open access: yesProtein Science, 1997
AbstractLinkers that connect repeating secondary structures fall into conformational classes based on distance and main‐chain torsion clustering. A data set of 300 unique protein chains with low pairwise sequence identity was clustered into only a few groups representing the preferred motifs.
