DNA coiled coils [PDF]

open access: yesProceedings of the National Academy of Sciences, 2005
We report the coiled-coil structure of DNA, which is generated by the dodecanucleotide d(ATATATATATAT). The structure has been determined by single-crystal x-ray crystallography. The molecules form duplexes with single-stranded overhangs, which associate with neighbor molecules and give rise to infinite double helices in a coiled-coil conformation ...

ARCIMBOLDOon coiled coils [PDF]

open access: yesActa Crystallographica Section D Structural Biology, 2018
ARCIMBOLDOsolves the phase problem by combining the location of small model fragments usingPhaserwith density modification and autotracing usingSHELXE. Mainly helical structures constitute favourable cases, which can be solved using polyalanine helical fragments as search models. Nevertheless, the solution of coiled-coil structures is often complicated

The coiled coil‐helix‐coiled coil‐helix proteins may be redox proteins [PDF]

open access: yesFEBS Letters, 2009
A number of nuclear encoded proteins are imported in to the intermembrane space of mitochondria where they adopt a coiled coil‐helix‐coiled coil‐helix (CHCH) fold. Two disulfide bonds formed by twin CX3C or CX9C motifs stabilize this fold. Some of these proteins are also characterized at their N‐termini by the presence of two additional cysteine ...

A seven-helix coiled coil [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
Coiled-coil proteins contain a characteristic seven-residue sequence repeat whose positions are designated a to g. The interacting surface between α-helices in a classical coiled coil is formed by interspersing nonpolar side chains at the a and d positions with hydrophilic residues at the flanking e and g positions.

Evolutionary Patterns in Coiled-Coils [PDF]

open access: yesGenome Biology and Evolution, 2015
Models of protein evolution are used to describe evolutionary processes, for phylogenetic analyses and homology detection. Widely used general models of protein evolution are biased toward globular domains and lack resolution to describe evolutionary processes for other protein types.

Multielement magnetic probe using commercial chip inductors [PDF]

open access: yes, 2004
A 60-element magnetic probe array has been constructed using miniature commercial chip inductors. The array consists of twenty clusters of three coils each mounted on a linear fixture.

Minimax Current Density Coil Design [PDF]

open access: yes, 2010
'Coil design' is an inverse problem in which arrangements of wire are designed to generate a prescribed magnetic field when energized with electric current. The design of gradient and shim coils for magnetic resonance imaging (MRI) are important examples

Design of a heterotetrameric coiled coil [PDF]

open access: yesProtein Science, 2009
AbstractWe have successfully designed a simple peptide sequence that forms highly stable coiled‐coil heterotetramers. Our model system is based on the GCN4‐pLI parallel coiled‐coil tetramer, first described by Kim and coworkers (Harbury et al., Science 1993;262:1401–1407). We introduced glutamates at all of the e and c heptad positions of one sequence (

Design and optimization of printed spiral coils for wireless passive sensors

open access: yesIET Wireless Sensor Systems, 2021
Monitoring physiological signals during regular life might provide many benefits including early detection of abnormalities and tracking the severities of diseases. A wireless connection between the passive sensor and the scanner eliminates the obtrusive

A crossover study to evaluate the diversion of malaria vectors in a community with incomplete coverage of spatial repellents in the Kilombero Valley, Tanzania [PDF]

open access: yes, 2016
Malaria elimination is unlikely to occur if vector control efforts focus entirely on transmission occurring indoors without addressing vectors that bite outdoors and outside sleeping hours.
