Metrics on RNA Secondary Structures

Journal of Computational Biology, 2000
Many different programs have been developed for the prediction of the secondary structure of an RNA sequence. Some of these programs generate an ensemble of structures, all of which have free energy close to that of the optimal structure, making it important to be able to quantify how similar these different structures are.

Structural Analysis of Secondary Babbits

Metallurgist, 2021
Repairing equipment with sleeve bearings requires a large amount of expensive babbit. Babbits have low hardness, low melting point, and increased ductility. They are run-in well in friction units, have high antifriction properties, and resist shock loads well.

On the secondary structure in mRNA

Biosystems, 1977
Abstract The sequence present in DNA phase transcripts have been investigated by Niyogi (1973) using a technique in which mRNA is enzymatically digested to yield different size classes that are resolved chromatographically into populations of equal chain lengths.

Protein secondary structure prediction

Current Opinion in Structural Biology, 1995
The past year has seen a consolidation of protein secondary structure prediction methods. The advantages of prediction from an aligned family of proteins have been highlighted by several accurate predictions made 'blind', before any X-ray or NMR structure was known for the family.

Modeling secondary structures and secondary structure linkages of protein sequences

2010 IEEE International Conference on Systems, Man and Cybernetics, 2010
In this paper we model protein secondary structures such as a-helices and b sheets and linkages thereof using passive electrical circuit components and obtain the frequency responses of these circuits. An analysis of the frequency responses of these model circuits shows that putative connections can be made between circuit behavior and known ...

Secondary Structure and Protein Deamidation

Journal of Pharmaceutical Sciences, 1999
The deamidation reactions of asparagine residues in alpha-helical and beta-turn secondary structural environments of peptides and proteins are reviewed. Both kinds of secondary structure tend to stabilize asparagine residues against deamidation, although the effects are not large.

Secondary structure of Qβ RNA

Journal of Theoretical Biology, 1977
Abstract The complete set of possible secondary structures of a variant Qβ RNA sequenced by Schaffner has been found using a computer program which allows G-U pairing as well as the usual Watson-Crick A-U and G-C pairing. Of special interest are those secondary structures with the highest double-strandedness.

Similarity of RNA secondary structures

Journal of Computational Chemistry, 2006
AbstractIn this article, we propose a relatively similar measure to compare RNA secondary structures. We first transform an RNA secondary structure into a special sequence representation. Then, on the basis of symbolic sequence complexity, we obtain the relative distance of RNA secondary structures.

The protein secondary structure flexibility

2008
Modeling protein flexibility is a long standing challenge in computational biology with a special impact to protein docking. Relating problems are protein structures alignment and identification of flexible and rigid protein regions, as well as a general definition of a region degree of flexibility.

Characterization of protein secondary structure

IEEE Signal Processing Magazine, 2004
What do proteins look like? Proteins are composed of fundamental building blocks of chemical molecules called amino acids. When a protein is synthesized by the cells, initially it is just a string of amino acids. This string arranges itself in a process called protein folding into a complex three-dimensional structure capable of exerting the function ...
